Also one thing you forgot to go over was the barra flexplate/flywheel bolts going loose! The barra guys do all sorts of stuff to stop them from backing out, some guys even tack weld the bolt heads to the flexplate/flwheel. The barra has 6 flywheel bolts and the 4200 has 7 bolts which is why the 4200 doesnt have issues with this and the barra does.
Australia is the go to place for Barra aftermarket support... The ford vs GM battle has been going strong here for over 50 years. Chrysler left the chat in the early 80's. The 6 cylinders have their own place in Aussie automotive history
Yes Australia has long been a 6 cylinder land - we got sick of your badly designed V8 rubbish. Nissan RB30E was the best engine EVER in a Holden - smooth & tough but reasonably fuel efficient ( we actually have to pay for fuel in Aus). BTW the Barrra was also used in the Ford Territory suv & it made these vehicles worth while as most others have rough pathetic turdbo dismal L4's
Would love to see a video like "800HP swap for $3000" or something like that with the parts needed. This would help people get started with the 4200. Keep it up!
Please me too I just got a 100$ well taken care of 4200 I believe it's an aluminum top but am trying to make a twin charged methanol ammonia injected with propane too....and am thinking I picked the perfect time to start rebuilding it..... gonna rebuild it with a aircraft aluminum mixed with boron pistons.... maybe the connecting rods to... make an alloy and send it to the Chevy garage or something
Lol body is rotten but tranny ....engine and everything else is mint... I love aluminum........ gonna try to make some nice high silica and graphite boron infused aircraft aluminum rods and pistons.... I'll make the alloy and have someon cnc it maybe an extra inch on the stroke and have someone make a deck an icy taller cylinders too
@@jerimiahrouillard6330 My wife has a 2002 GMC Envoy that she wants to junk. It runs well, but is rusty. After seeing this video, perhaps I should keep it and pull the block for the giggles.
The oil drain is actually the "side effect" of the hollow tubes on the side of the block, rigidity is the main purpose. You will always get more stability out of a hollow shape than a solid piece if you use the same amount of material. I worked in a foundry making engine blocks and cylinder heads for 20 years btw, making blocks for Humvees and heads for Cummins. In Germany lol
@@Calvin-Nelson absolutely! :-) I remember my company experimenting with different things over the years, hollow cam shafts, cast-in in between cylinder cooling, thin wall castings with, a crank case thickness of only 2.5mm
My father recently passed and left me his his trailblazer. I was starting the process of purchasing an ls2 to put into it. My friend told me abkut the engine and its berra resemblance. I found this channel. I cannot thank you enough. My dad would have loved to play with this engine. Thank you sir. God bless
We’ve gone 700+ on stock NA FG barra’s with no issue at all. And Australian dyno’s read very “differently” (read - realistically) from what we generally see over here. Also no need to install pump gears unless you’re a big fan of the rev limiter, however yes. We always replace them. The valve springs are the general first limitation.
@@Calvin-Nelson probably a safe place to pull up really! Definitely good to see the 4200 platform getting more traction however! Seem like a good alternative that’s locally available for you guys!
@Calvin-Nelson 450 is about the limit of the stock transmission, but if you're going to the expense of a trans swap then it's likley you'll be doing engine mods too
All of that is correct. A $1000 wrecker mid BF to FG greentop barra (LPG), add head studs ($300, diy, no need to take the head off), valves springs $300 also diy, and cams will give 540rw kw without opening the engine. Peolple have done this and increased boost until this mostly stock engine lets go. 545rwkw on a mostly stock green top barra. = approx 850 crank hp. The red top is not the best at all, I know, have one running only 440rwkw all day, on e85. You do not need to add oil pump gears on an automatic barra that is not banging of the rev limiter. That is a myth.
Good comparison. Similar but different. I still think GM should have kept the Atlas platform. They are pretty good at canceling anything that is successful. Hope your Dad is doing OK. Give us an update on him.
Yeah. I think it would have stuck around if they hadn't nearly gone out of business in 2008-2009. They closed the only plant that produced the 4200 and thus it was dead. The 4 and 5 lasted til 2012. Will do. Thanks
barra was sold in australia and new zealand, billet oil pump gears and stiffer valve springs are the only "internal" mods necessary to run 700 rwhp on a daily driven barra turbo and it's not unheard of for them to turned up even more at the strip. there is no issue modifying a barra sump usually not necessary as you have options but still that's an imaginary problem the sump and the windage tray are the girdle, the main reason for billet girdles in place of the tray is to accommodate aftermarket rods. never heard of any oil drain back issues and the oil drains are huge compared to a lot of v8's so another non issue. who told you australia didn't mess with v8's, a lot of v8 design and improvement for both ford and gm has come from australia. so why do we use 6 cylinders it's all about performance and reliability the commodore needed a 6.2l ls3 just to get close enough to see a stock xr6t cross the finish line.
Hurricane is right you did say V8s weren't common when in actually fact V8's were bloody everywhere & from both manufacturers. There was a bit of information that you probably could have researched a little more so as to not sound so one sided.. I did have a laugh when you said 800hp from that drum dyno🤣🤣🤣. 800hp....You are a funny guy🤣🤣
I think this is semantics.. The point is that V8's were less common here than the U.S. much less common. We never got big blocks for a start, basically our small block was a six, and our big blocks were small block V8's.
@@potaka79 compared to the US they are not as common in AUS, its not drastically different but definitely not as common. Nobody needs multi-tier licensing to own a V8 car/truck in the US and the majority of families have one or more V8 trucks/SUVs
I think you are bang on, the Barra though was a continuing evolution of the Australian Ford I6 for decades where the 4200 was a fresh design for the GMT360-370 chassis.
Based of an American engine of the 60s 😅😅 all they did was move the camshaft up and then added another, relax, not much innovation tbh. Speaking as an Australian ofc
Good comparison between these engines. I'm a big fan of hot 6's and have known about the Atlas for a while. You did a good job of pointing out the pro's & cons of each. Much appreciated.
Had a 4.2 vortec back in the day that i sold at 280k miles. 4 years later it was spotted still on the road. God only knows with how many miles. Very strong motors. I hope they take off in the aftermarket scene
Nice video mate, only thing I need to mention was the Barra came from the factory with only 2 conrods, the 1r and the 3r. The gas motor has different pins though and higher comp pistons. And legend has it that after July 2006 a lot of the NA motors got the same rods as the turbo motors, a lot of the later NA motors are used to make 600+ wheel HP with aftermarket oil pump gears and valve springs
Awesome ep. Slight correction on the trans issue however, you can buy multiple bellhousings to suit th400, powerglide, c4 etc. you can cut off the oem bell and bolt the conversion bell to the pump bolts. Companies like Circle D also offer drop in converter options state side. Also we’ve never seen any issued with oil pooling in the cylinder heads. RB’s however suffer massively from oil pooling
best part about my barra is it come in a 2010 sports and luxury edition ute. Full leather, wireless car play, big stereo, heating and aircon, cruise control, Haltech ecu and dash. 750rwhp with some bolt ons and a tune
Had two 4.2s, after driving 4.3 Vortecs for a while. Great engines, never ever used any oil, gas mileage was always consistent, power was on point and excellent. I chirped the tires a few times on both. Driving a 5.3 Tahoe right now, got an LS1 Camaro in the garage. Looking for a Corvette (found an LS6 Lingenfelter in another state today--contemplating...hmmm).
My friend had a Chevy trail blazer. 2004 I was so impressed with the moloader I ended up. Purchasing a 2004 Isuzu accender it had 60000 miles when I bought it. Miles when I bought it. The truck has been such a blessing. Now pushing over 300000 miles. Drove that truck to Canada from Florida. 60 below 0 with no garage. Never add an issue firing up. There. 's no red line on the dash factory 10000 rpm valve Springs. 292 horsepower. With the rear end, it got not too many people's just gonna blow by me. I'm so impressed with that truck in that motor. Oils can change to every 3000 miles. And hasn't been completely beat on any other stories. I would love to hear. Thank you.
The greentops being mostly for taxi’s are built like tanks and very reliable, they’re infamous for being capable of pushing upwards of 1,000,000km on the odometer
It’s too bad that GM never made a sports car with the 4200 Vortec. It would have been really cool to see in a Pontiac or something like that. I’d imagine it would rival the other 6-cylinder sports cars at the time and possibly give the LS engines a run for their money. This engine could have saved Pontiac. But sadly it wasn’t meant to be.
That's an excellent point , especially surprising considering Pontiac had the 3.8 supercharged V6 they used in the Pontiac GTP... they could have put a Supercharged 4.2 in the Camero or reinroduced the ' sport coupe or a 5 Dr. wagon, similar to the Dodge Magnum Hemi..
As a huge fan of the Barra, I am totally chuffed to know about the 4200 here in the states. As you said, I can see a lot of interest in this engine developing. I get so bored with the same old SBC builds over and over. BTW, has anyone tried to carb one of these? Look awesome with 3 Webers!
1:40 Surly someone has mentioned this already but the FalconBarra's were also available in New Zealand. (Just like previous iterations of the Falcon were available in NZ) We seem to be Australias snot nose shady younger brother always trying to rax big bros toys and jumpin all in on their hand me downs Edited due to excessive amount of cones...
And south africa, and the odd aisian country (taiwan iirc, a couple of territorys went over?) And word on the street is the US got barras in some forklifts, although ive never seen proof of it. If that is indeed true, you should be able to get random gaskets.
Came in the H3 Hummer as well. I have been upgrading mine. Got a super nice header coming from Sanderson Headers in San Francisco coming this week. Also I'm surprised no one is trying to steal the front calipers off the H3. They are 4 piston and look like what is on a 2010 and newer Camaro. They are bigger than what was on my 2001 Silverado with a 4.8 LS. If you really dig into the H3 they were over engineered in a lot of ways.
@@Calvin-Nelsonhere is the answer I was looking for. I thought the Colorado engine was the 5 cyl. Thats not the same in any way then. So not worth trying to boost & all that.
wow that was very thorough! You must have fun putting your foot into it once you dial it in! I have a 2008 Trailblazer, bought it because of the inline 6, didn't realize it was that special. It has been very reliable and great in the snow!
Both are great engines, the 4200 probably would've done well in australia as we seem to love 6cylinders and big turbo's A few things to add RIPSS that 2200hp barra that still runs a stock head with minimal work. so breathability definitly isnt a issue and to add it still uses the factory oil drain setup (car is setup to be daily driven) it doesnt suffer the same fate as the RB platform Transmission situation isn't as hard as you put it, its quite easy. plenty of places sell adapter plates or complete bellhousings that'll pretty much to go any transmission, i bought a th400 bellhousing not long ago for $150usd. Oil pump is really only an issue if you plan or sitting at high RPM or bouncing off the limiter, we have plenty of 600-800hp cars still using factory gears (which im not a fan of but they still do it) There has been a few guys making 1000-1100whp on the Gas rods, (im still skeptical but they have dyno footage to prove it) I seen a comment about Flexplate bolts ( stop using stock or shit bolts). a nice set of ARP bolts on a nice flexplate solved any issues.
Since the front axle goes throught the 4200s oil pan on 4x4 models, would it be possible to mount it backwards in the back of a car as a mid-rear engine? Or would that cause some oiling issues if its facing backwards?
@@Calvin-Nelson I don't mean just the oil pan, I was thinking of having the whole engine facing backwards in the back of a hatchback or something with a trans and transfer case in front of it and driving the rear wheels with what would have been the front diff. I'm just wondering if there would be any issues with oil getting thrown to the front of the engine under acceleration. Thanks for replying.
I really enjoy watching something different at the starting line, racing what you have. It's crazy what those guys down under are getting out of 4 liters. There's an ancient saying; "That to finish first you, first have to finish". That 4.2 sure fits the bill, 800 hp with a bone stock bottom, pull after pull, wow. Your thoughts on bell housing patterns are spot on also, power has to make it to the tires. Keep making the videos, I'll keep watching. Can't wait for the header showdown. THX.
Im a Ford guy but appreciate power and availability of parts, i have a Barra in my F100 but have 0 intentions to go over about 600whp. I also want 400whp in my Opel and will be using the Atlas 2800 4cyl but its a beasty fella for the room available without butchering the car too. All about what aggravation you are willing to work thru, you have proven the 4200 is worthy and the Barra has been proven so its up to the brand loyalists to choose now lol
Where do you get performance parts for these engines?? I've got an 04 trailblazer that's going to need new rings pretty quick here and I'd love to build it, and how do you guys go about tuning these engines?
The cressida in my profile pic has a sbe fg turbo engine, has cams, studs, springs and pump gears, has made 900rwhp through a glide and has done for years, admittedly it doesn't get turned up that much very often and all the power is up top to keep the rods happy. There is a video on my channel on the dyno where it made 800rwhp but has been turned up since then when it went 900. Great upload mate 👌
If you spend enough you can get a tonne of power out of the Barra. There is a video of an orange Falcon that did 2200hp at a Summernats meet. The green top was an LPG engine with strengthened valve sleeves.
Questions What type of valve materials? Stock exhaust intake flow @.5 and max valve lift Camshaft options Stock and aftermarket compression ratio Long block weight
You are the Atlas champ. I know you aren’t the only one, but you are the main one. As it gets used more and more, it will all point back to you. That has to feel kinda cool.
Ive seen factory turbo Barras make over 700hp complete stock internals with a bigger turbo, pump and injectors, pretty safely, they are just an ideal platform to get power out of relatively cheaply
@@Calvin-NelsonThat is a plus 😅 the price of them has gone stupid along with just about everything else good from Holden and Ford after they shut down here..
Calvin, I follow several Australian YT'ers (eg: Ben Neal and his Cresta with TH400 trans). 1st comparison I've seen. A Barra in a '66 Mustang fastback would rule, but you'd have to airfreight spares. There's a '68 4 door Nova in my neighborhood that would be an ideal Vortec sleeper ☺
i had a 2006 trailblazer in 2016 till 2018. i knew what i had but i was 18 and broke so i ended up braking the motor sadly from lack of oil... young and dumb. im glad ive finally found a channel as obcessed with this motor as I am.
Theres 3 variations of the "red top" engine. From 2002 to 6-2006 they had thin garbags rods. After that they had bigger rods and 10-2008 they released the engine with stainless steel valves for the new body shape FG falcon. Late model FG turbo barra or late FPV "blue top" barras are the best
In Aus Its basic finance. A barra will give you more HP per dollar than any other engine available to us. There is A LOT of 6-800hp barras on the road that do the school and shopping run during the week and then chop big dollar V8's at the drags on the weekends. And If you break it there is a miriad of spares both new and used available.
The grey and early green top has what you would call 1r23 rods which are the na rods, then the later green tops and the turbo rods have 3r23 rods and they are substantially bigger. The difference between the two 3r23 rods is the turbo engines have a fully floating wrist pin and the lpg and na engines have a press fit pin
Ok, Ford Australia used to offer the Falcon with a 302, but the 302 did not make big HP, they had been quietly working on the 6 cylinder engines and found they could more than match V8, the name Barra comes from the Barramunda fish, the Barra is a relation of its predecessor the Intech SOHC!! i know there is a Barra in Australia 1200HP!! Never heard of the other engine.
Had a 06 Trailblazer and have to say the engine was silky smooth and delivered power pretty well. The 4sp auto tranny didn't help much for great power delivery but it could get out of its own way when prodded.😊
Im australian, me and my brother who has a dyno shop bought a falcon with the NA barra 6. Has 350000kms on the clock. Didnt change any internals or even the oil or fuel lol. It went from 206rwhp to 306rwhp with 7 psi boost. To me that is very very impressive. Had a commodore with an GM L67 in it (supercharged 3.8L V6) running 8 psi and it made less than 200hp (they were 165kw at flywheel from memory)
Idk man that’s a tall order for a 4200 block even with the weight break you would have to make 1900+whp to run in the middle of the pack and the front runners in the class are making 2400+! I would try ultra street with one first but even then it’s not gonna be easy and then your gonna need a 150,000 dollar roller with carbon and titanium everything it would be badass combo though!
Although we have a love for hot 6s in Aus ,v8s are just as popular here lol We had a huge v8 obsession all the way up to the late 90s which is still alive today 👌 A lot of U.S. ls guys are using Aussie ls parts like plazmaman, pwr, haltec etc. Great comparison between the 2 engines though 👍 Good points on the ease of getting parts staying with locally available engines. I wouldn't use a 4.2 when the barra is readily available and cheap 👍 Actually buying a fg falcon xr6 turbo myself shortly (2008-2015) for my new daily/weekend fun car, going for 500whp which is plenty in a street car, can run on pump 98 (your 95) and will still maintain reliability 👌 We're not only kings at barras but Nissan rbs and rotory's too 👌🤣
I love what you guys are doing with all the platforms. All I meant by the V8 statement, is V8 stuff is way more common over here. We got the truck LS stuff, so it makes it a natural choice. The RB stuff you guys have developed is awe inspiring
Have been with the old one from the big three 250 chevy, 300 Ford, 258 AMC, but LOVE The BARRA. Never got one and never will ...... The comparison was outstanding and I did not know about the 4200 Vortec from before, but the Pontiac overhead cam inline 6 was a brilliant in its time. Thanks for all the good info, just amazing know how......
Small correction about the Barra's availability - It was also the engine dropped in to the Ford Territory, which was a mid sized SUV available in RWD and AWD, and with Turbo fed variants. The Territory is probably unknown in the US, bloody brilliant car when released, but suffered from Ford US controlling the corporate budgets, and deciding the Ford Everest, made in a country where Ford could underpay workers, was cheaper to import to Australia then it was to build the Territory. The biggest travesty is that the Aussie made SUV was not allowed by Ford US to be built or exported to LHD countries, same as the internal embargo placed on the Aussie Falcon at the very same time that GM was doing LHD Commodores to send to the US as Pontiac G8's. If you lot had gotten the BA and FG series, you would have been shocked at the ride and handling performance, let alone the FPV F6 spec cars. One of the reasons Ford US spat the dummy over the Falcon's and Territory's, was because Aussie buyers had soundly rejected the FWD Taurus, which was pitched as a new luxury model priced above the Falcon, but was of such shitty build quality, ride and handling that no one that drove it wanted to buy it, when Ford US had decided to try drop the Falcon's in the late 90's, and replace them with RHD imports.
Ford Taurus, a friend had as a company car i drove and it was unfun. lots of comfort tech but ugly and a shitty drive. 1998 I hired a FORD Taurus in LA drove to Las Vegas via death valley and to Grand canyon and back to LA. It was a far better car than the RHD shit boX Ford sent to Australia.
I wanted a Barra after watching the Aussies. But now you make me want a 4200. This coming from someone who has a few Coyotes (and a few GM "LS" swaps).
As for stock potential power the Barra was competing in a market were fuel consumption was a bigger deal were the Atlas was competing against V8s so the rods was one place the Ford engineer's could save some weight. Keep up the 4200 videos 👍🇭🇲
Ba falcon series 1 engine had the weak conrods stock, bf series 2 conrods and onwards were improved significantly. I've seen figures of 700hp with nothing but boost and valve springs
VERY glad you made this. There is not a good unbiased review online that i could find. Doing gods work- you are a pioneer in the journey of the aftermarket swap world of 4200s
For those talking about the flex plate bolts; yes they do have a habit of backing out, got nothing to do with how many bolts it’s to do with the thickness of the flex plate, it’s thin so clamping force and vibration are the problem,usualy after market thicker flex plate or a simple bolt locking ring will fix it,been there done that,and for some a little weld on the bolts but not really recommended
Epic. Can't wait to see how things progress further. However, I also want more focus on the 5-cylinder Atlas since that'll actually fit in my application. That, and a 90mm de-stroke crank (for both) if possible. IMO 90mm is the best stroke for a street car, 8000rpm capable at only 24 m/s piston speed. The ultimate goat would be if all of that was doable ON TOP of a diesel conversion, but that's because I'm too much of a min-maxer trying to have my cake (fuel economy) and eat it too (power).
There's a work truck tax on the 4/5 cyl Atlas so they're less attractive compared to GM car engines like Ecotecs and V6 options that make more power at less weight/size/cost.
@@mattbirt114 now that's interesting. Seems to be completely different from how it works over here in Germany. A truck registration for a car can save you some car tax money. The specific engine type doesn't matter. So, for example, one may get a truck registration for a VW rabbit by taking out the rear passenger seats and removing the rear seat mounts to make a transporter out of it, this will save tax money for the exact same engine.
@@nopadelik9286 Lol German literal English interpretation moment. Ok, it's not an actual tax on the used engine. They just cost more than they should, like 10x what a 4200 costs ($3000 vs $300).
Both ford and gm don't make them any more so what's modern equivalent? BMW, Mazda, or Stellantis??? Mopar is selling Stellantis crate engines in different hp outputs ...
Have you considered building a "I've been telling you guys!" 4200 for a little head to head dyno competition with some of the aussie guys? That could make some good headway on attention to the platform! I've been really impressed with the 4200's capabilities. An it IS a shame you don't see more builds out there. Hope all is well with you an yours. Take care 👍
I killed a 4200 by driving it for a month with no oil, it finally let go when I redlined it. I was going 40k miles between oil changes until it died at 200k
The LS V8 actually was available as early as 2003 in the GMT360 / 70 (Buick Rainier, and long wheel base versions of the Isuzu Ascender, Trailblazer, and GMC Envoy) platform as a 5.3 until the Trailblazer SS came out in later years. I have an 03 Envoy XL with the 5.3 but I originally wanted one with the 4200 until I figured out there wasn't really any performance aftermarket support for it.
Wish GM would have stuck with the original TBSS concept, the turbo 4.2 making 400hp. If they had then there would have been a ton of aftermarket support available
I'm a Aussie so that 100% makes it only a Barra for me. I'm currently collecting parts to build a 67/68 Mustang for Barra power. I have a early XF 1990 ute im using the T5 from. Can use the 1990 to 2001 OHC 6 T5 bellhousing to adapt a earlier T5 so the shifter is in the right place I could fit a Windsor but as I "Only" want 400hp a almost free Barra is the cheapest and simplest option Grey top, standard computer with smart lock removed and locally available factory wiring harness modified for 3 wire connection.
@@Calvin-Nelson no, it’s unique, basically we had the 200 log head a direct copy of the USA 200, became a 221 for XT Falcon in 1968. From then to the Falcon Crossflow steel and alloy head right through to the end of the pushrod Falcon 250 in 1990 was the same bell housing pattern as the mid 1960 USA engines. (There was a 3 or so years when both push rod cross flow and SOHC 4 litre was made by Ford Australia) When the EA Falcon came out in the late 1980s with its SOHC engine, it came out with a new bigger bell housing pattern that was used right to the end of the Barra production. There might be variations of bell with thread sizes and dowel placement but my understanding is it’s the same 1988 to 2017
@@Calvin-Nelsonthere is a lot of support to run gm automatics, and they also run the ford c4 autos, the btr 4 speed they come out with are very terrible, they also offered them with a zf 6 speed derived from the European BMW's, jaguar and others that ran that, in manual trans they where offered with the t5z, t56 and tr6060 in the fpv models, so there is quite a lot of options
yes, ever since i found your older videos making the Atlas a power house and been closely following cuz im oogling a trailblazer that blew her headgasket and has been sitting after that... this just gives me hopes that support ramps up and lowers prices so it becomes accessable to me
Oh no! You had better throw a chair through a window and leave the shop doing a burnout through the parking lot, the grass, the shop, and hell get up on the roof with it as well! Then sit down and tell us how everyone was against you from the beginning. 😂
246K on my stock Trailblazer 4.2 and it has the original trans. I did change the trans oil and filter once. Sometimes I suck about 4 quarts out through the dipstick tube and then add fresh oil. Just changed motor mounts, valve cover gaskets, intake manifold gaskets, front brake rotors and pads, front wheel bearings, and rear brake pads. Out of frustration, I ripped out the module that changes from defrost to floor to dash and threw it in the yard. So, it now only blows from the dash vents. Now, I need to change the temperature blend door actuators and I'll be good. LOL. Changed a lot of front-end parts and motor mounts throughout the years. In my opinion, the Trailblazer 4.2 is one of the best vehicles ever made, apart from a 1962 C10.
I always felt like the Ford 6.2L (offered in the super duty, 1st gen Raptor) is gonna be like these inline 6’s. Great performance capable engines just not recognized until later.
I have a 06 Trailblazer EXT with a 07 engine, son blew up original. Thought this 4.2 would be nice in a late 50's-early 60's Jag sedan, but I have been seriously thinking about putting whole frame and electronics under a 41 Ford Super Deluxe sitting in my drive way I think I saw you in the Nova a couple years ago. Fantastic what you have done with this platform.
Funny that you made this comment. Ive been in the process of putting a 4200 in my 55 Jaguar Mark VII. Fits like a glove so far. Still working on getting it running.
That was very interesting and informative! I've been thinking about trying to build a /6 mopar engine. Of course I will definitely need someone who actually knows what they're doing to help guide me but I've seen a few pretty quick ones and I always thought that it would be cool to run one in something like a little Plymouth Arrow. Great Video!
Yo dude good try but bathurst 1000 is a v8 race between ford and holden its huge and the reason why they stopped producing the falcon xr8 was because the barra turbo was just flogging everything out of the water and the barras where also found in the territory. Im 2 min into the vid mate.
It's a shame Holden didn't use the vortec 4200 in the commodore that would have made for some interesting competition between the two especially if they made a turbo version.
Both WAY better than a small block v-8 or Japanese I6. Amera Barra Haters "Imitation is the highest form of flattery" These engines are both incredible with factory blocks. If the crank journal sizes are close enough( I am guessing based on my engine building experience) you could potentially use the slightly longer Barra rods in the 4200 along with some .025 overbore Barra pistons. Wrist pin height vs block deck height being the main concern.
@@alexinnewwest1860 The amount it takes to get them there is.... EVERYTHING. So yes they exist but no I don't personally believe the small block are better than the big blocks. Use to run LS engines in my rail on alcohol and would use up between 2-3 a season. Switched to a 454 based block in 2017 and have only rebuilt it 3x's. No broken cranks or blocks. My point being yes the smaller engines can make the big dyno numbers but their not going to live as long at those extreme levels of cylinder pressure as well as a larger displacement engine with more material to spread the abuse across. The crank main, and rod journals are quiet a bit larger on the US engines as well as the block and head bolts...... The Japanese engine I have mad respect for but STILL NO REPLACEMENT FOR DISPLACEMENT.
@@ProjectFairmont Love a v-8 as much as the next guy but here are the facts like em or not. Basic I-6 Architecture dictates if all things are equal the I-6 will have more power and durability per/L. I-6 has 120 degrees of crank rotation to apply power on the power stroke. V-8 has only 90 degrees. I-6 has only 1 connecting rod per crank journal, all V engines share crank journals. More main journals per cylinder ie. i-6 has 7 mains for 6 cylinders when counting end journals a V-8 only has 5 mains when counted the same way. IN addition A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. These are mathematical principals that transfer to engineering advantages. So yes WAY BETTER. These are the reasons over the road diesel in big rigs were rarely V-8's. Nearly all I-6's.
@@playanddisplay3636 like I said, a fan. Nothing you said I don’t already know, god bless ‘em. However, to say way better than V8? First of all early I6s did not have cross flow heads, is that a deal breaker, maybe maybe not. Fact remained it took more work to make ‘em work than a small block V8 cause they were smaller in displacement and couldn’t rev without major flow work. The Ford 300 is a long lump of an engine to go racing in a car. There is a huge gap between those anvil tough but crude sixes of the 50/60/70s and the Barra we never got (based on the OG US Falcon six) and the 4200. Filled kinda, by the 2JZ, and BMWs mostly. But still not critical mass. V8’s on the other hand have steadily improved and offer bang for the buck by virtue of availability, aftermarket support and basic robust qualities. Now if I was in OZ or NZ I would be all over the Barra haha!
Love both engines. The Barra's issue is logistics, and transmission issues. The 4200 is aftermarket support. Would that 4200 fit in my 49 Studebaker pickup?
I hope some company further invests in the 4200 in the future, to the point of CNC-machining blocks and heads and 3D-printing whatever else is required. It surely deserves.
@Calvin-Nelson I think the only issue would be the balance shafts with the i5 am I correct? You could put forged internals in it, but without the balance, it would just shake itself apart.
Mate as an Aussie and a supercharged Coyote owner that’s all ex factory your Barra assessment is fair in relation to zones, and availability well and truly ; check out engine power on their slant 6 build and having to source inlet manifold and stud girdle/ rocker set up from Australia hence the wait before doing let alone filming build
Very cool video! I knew some about these engines but that was really interesting to see all that info. I'm personally a huge fan of the Ford 300. I'm so happy seeing people trying to fit in LS heads to them nowadays. I am not sure I've seen a successful street version yet, but still awesome. Hopefully the Dodge/ Chrysler/ Fiat/stellantis new inline 6 will be able to be added to the mix in the future when we can start grabbing them up in junk yards. Hopefully they fit yhem to a lot of vehicles so they'll be easier and cheaper to get.
Hey Calvin. Great video. Really informative. I assume the lower frontal area of an I6 compared to a V8 might make it attractive for some speed records. Has anyone taken the Vortec to Bonneville? And when can we expect to see you competing with the Stude? 😁
yes. The Vortec 4200 holds a couple records at Bonneville actually. Almost done with break in on the Stude, so probably 2-3 weeks you should see a video.
@@Calvin-Nelson is there any predecessor to either, in the form of cam in block OHV, or successor that changed in name but was upgraded? Such a shame as the inline 6 is inherently so good
@@WesternReloader Unfortunately, no. It is a one off. Shares nothing with any other generation. They did make a 4 & 5. Apparently the Aussies got the 5 cylinder in the H3 Hummers.

I have a 2002 BA turbo sedan which is one of the very first turbo barras made, it's had mild mods and a tune (using sct's Xcal3) and makes 290Rwkw or close to 400hp at the tires on a rolling road chassis dyno. Has been that way for over 11 years now and is still reliable as. No replacement oil gears in the motor (as claimed required at 5.59 in vid) or head studs etc, just upgraded valve springs so not sure why you'd be needing to do oil gears on a mild motor. Also guys in Aus have boosted the grey top "weak" internal engine to over 420Rwkw (563HP @ tires). Alos have a 2003 BA Turbo ute making same power with same mods as the sedan, only thing thats really failed with both has been the BTR 4 speed auto when in stock form, rebuilt and beefed up a little they have performed well. The main rule to longevity is all in the tune.
That's great man! I'm just going off what I've read on the internet and seen in videos. Hard to know all the facts when I'm not immersed in it. I think I got most of the major stuff correct. Sorry I missed a few of the minor items. 4200s can go 600+ whp (450+rwkw) without touching anything. (No valve springs, or oil pump gears) you can also hang out on the rev limiter no problem too.
@@Calvin-Nelson The reason I mentioned the valve springs was relative to my 2 BA's as they had the weaker springs which were upgraded in BF on models. In BA they would get valve float from as little as 10psi where as BF/FG/FGX will go 15psi on stock springs. Plenty of skid kids getting into NA barras around the place and they seem happy sitting on the rev limiter as stock engines, sure going more than mild oil gears would be good insurance but as said, in stock form, skidders are popping tires and blowing diffs left right and centre with the engine bouncing off the limiter yet holding up fine. All good for the 4200s for you guys there as you correctly point out they and the Barra are very close in most areas and clearly both good 6's. At the end of the day you use what you can access easily.
I'm confused how the 4.2 doesn't bolt directly up to the same transmissions as the LS when they have been used in the same applications interchangeably... Did they have different transmissions for the same cars based on if they were LS or Atlas engines?
Also one thing you forgot to go over was the barra flexplate/flywheel bolts going loose! The barra guys do all sorts of stuff to stop them from backing out, some guys even tack weld the bolt heads to the flexplate/flwheel. The barra has 6 flywheel bolts and the 4200 has 7 bolts which is why the 4200 doesnt have issues with this and the barra does.
4200 has 8 bolt. I was going to mention that, but I didn't want to get called out for being incorrect. I saw Adam LZ had trouble with that on his.
holy crap your right i was going off pure memory, thats awesome. The 4200 def in the sub 1500hp range is a superior platform IMO. @@Calvin-Nelson
Explain exactly why having 6 flywheel bolts causes them to back out
100% the achilles heal of Barra… we suffer from it regularly
@@BennysCustomWorks Someone should make a billet with 4200 style bolt pattern with a flexplate to match!
Australia is the go to place for Barra aftermarket support...
The ford vs GM battle has been going strong here for over 50 years. Chrysler left the chat in the early 80's.
The 6 cylinders have their own place in Aussie automotive history
Yes Australia has long been a 6 cylinder land - we got sick of your badly designed V8 rubbish. Nissan RB30E was the best engine EVER in a Holden - smooth & tough but reasonably fuel efficient ( we actually have to pay for fuel in Aus). BTW the Barrra was also used in the Ford Territory suv & it made these vehicles worth while as most others have rough pathetic turdbo dismal L4's
Man I’d love to have a nice Barra motor for a mid size pickup, 5-6 spd manual wow ✌️🇺🇸
I've got a sleeper rwd Territory. It's fun when I turn the traction control off. 😉

Can do.
Please me too I just got a 100$ well taken care of 4200 I believe it's an aluminum top but am trying to make a twin charged methanol ammonia injected with propane too....and am thinking I picked the perfect time to start rebuilding it..... gonna rebuild it with a aircraft aluminum mixed with boron pistons.... maybe the connecting rods to... make an alloy and send it to the Chevy garage or something

@@jerimiahrouillard6330 My wife has a 2002 GMC Envoy that she wants to junk. It runs well, but is rusty. After seeing this video, perhaps I should keep it and pull the block for the giggles.
@@Calvin-Nelson make this.. 😢
The oil drain is actually the "side effect" of the hollow tubes on the side of the block, rigidity is the main purpose.
You will always get more stability out of a hollow shape than a solid piece if you use the same amount of material.
I worked in a foundry making engine blocks and cylinder heads for 20 years btw, making blocks for Humvees and heads for Cummins. In Germany lol
Either way, I'll take it!
@@Calvin-Nelson absolutely! :-)
I remember my company experimenting with different things over the years, hollow cam shafts, cast-in in between cylinder cooling, thin wall castings with, a crank case thickness of only 2.5mm
so you are partially to blame for all the poor quality cruft. (Germany!)
Strength to weight, yes hollow is stronger but same size and shape no. People often get this confused.
@@throttlebottle5906thought the same thing. Good try tho.
My father recently passed and left me his his trailblazer. I was starting the process of purchasing an ls2 to put into it. My friend told me abkut the engine and its berra resemblance. I found this channel. I cannot thank you enough. My dad would have loved to play with this engine. Thank you sir. God bless
Sorry to hear about your Dad passing. Stay strong!
We’ve gone 700+ on stock NA FG barra’s with no issue at all. And Australian dyno’s read very “differently” (read - realistically) from what we generally see over here.
Also no need to install pump gears unless you’re a big fan of the rev limiter, however yes. We always replace them. The valve springs are the general first limitation.
Fair enough. Most I've seen claimed was 450whp.
@@Calvin-Nelson probably a safe place to pull up really! Definitely good to see the 4200 platform getting more traction however! Seem like a good alternative that’s locally available for you guys!
@Calvin-Nelson 450 is about the limit of the stock transmission, but if you're going to the expense of a trans swap then it's likley you'll be doing engine mods too
All of that is correct. A $1000 wrecker mid BF to FG greentop barra (LPG), add head studs ($300, diy, no need to take the head off), valves springs $300 also diy, and cams will give 540rw kw without opening the engine. Peolple have done this and increased boost until this mostly stock engine lets go. 545rwkw on a mostly stock green top barra. = approx 850 crank hp.
The red top is not the best at all, I know, have one running only 440rwkw all day, on e85.
You do not need to add oil pump gears on an automatic barra that is not banging of the rev limiter. That is a myth.
@@Calvin-Nelson im running 600whp on stock pump gears, car in profile pic
You're amazing for being one of the first major 4200 tinkerer. Can't wait to see more of this engine
My 4.2 is still running great with 294k miles. Original transmission too which is a little scary to think about sometimes.
Nice! Mine has 324k of absolute abuse and still running strong. Now I'm ready for a turbo

@@Emilthehun had to rebuild my 4L60E in my 2002 suburban @ 330k miles.
Good comparison. Similar but different. I still think GM should have kept the Atlas platform. They are pretty good at canceling anything that is successful.
Hope your Dad is doing OK. Give us an update on him.
Yeah. I think it would have stuck around if they hadn't nearly gone out of business in 2008-2009. They closed the only plant that produced the 4200 and thus it was dead. The 4 and 5 lasted til 2012.
Will do. Thanks
barra was sold in australia and new zealand, billet oil pump gears and stiffer valve springs are the only "internal" mods necessary to run 700 rwhp on a daily driven barra turbo and it's not unheard of for them to turned up even more at the strip.
there is no issue modifying a barra sump usually not necessary as you have options but still that's an imaginary problem the sump and the windage tray are the girdle, the main reason for billet girdles in place of the tray is to accommodate aftermarket rods.
never heard of any oil drain back issues and the oil drains are huge compared to a lot of v8's so another non issue.
who told you australia didn't mess with v8's, a lot of v8 design and improvement for both ford and gm has come from australia. so why do we use 6 cylinders it's all about performance and reliability the commodore needed a 6.2l ls3 just to get close enough to see a stock xr6t cross the finish line.
I never said that the V8 stuff wasn't done in Australia, just it is less common. You guys didn't get the truck LS stuff.
Hurricane is right you did say V8s weren't common when in actually fact V8's were bloody everywhere & from both manufacturers.
There was a bit of information that you probably could have researched a little more so as to not sound so one sided..
I did have a laugh when you said 800hp from that drum dyno🤣🤣🤣.
800hp....You are a funny guy🤣🤣
I think this is semantics.. The point is that V8's were less common here than the U.S. much less common. We never got big blocks for a start, basically our small block was a six, and our big blocks were small block V8's.
@@potaka79 compared to the US they are not as common in AUS, its not drastically different but definitely not as common. Nobody needs multi-tier licensing to own a V8 car/truck in the US and the majority of families have one or more V8 trucks/SUVs
I think you are bang on, the Barra though was a continuing evolution of the Australian Ford I6 for decades where the 4200 was a fresh design for the GMT360-370 chassis.
Took 3 different engines and made 1 on a clean design, like the LS was clean design
Based of an American engine of the 60s 😅😅 all they did was move the camshaft up and then added another, relax, not much innovation tbh. Speaking as an Australian ofc
Good comparison between these engines. I'm a big fan of hot 6's and have known about the Atlas for a while.
You did a good job of pointing out the pro's & cons of each. Much appreciated.
Thanks!
Had a 4.2 vortec back in the day that i sold at 280k miles. 4 years later it was spotted still on the road. God only knows with how many miles. Very strong motors. I hope they take off in the aftermarket scene
That seems to be the trend that I have seen. The body usually rusts around the engine, or the transmission quits.
@@Calvin-Nelson Up here in the rust belt, the rear axles fall out
The GMT360 line of vehicles are widely regarded as the least reliable modern vehicles in automotive history
barra zf 6 speed autos are fairly strong or you can just go manual and use a tr6060 or t56 all of these are strong factory options for the barras
Nice video mate, only thing I need to mention was the Barra came from the factory with only 2 conrods, the 1r and the 3r. The gas motor has different pins though and higher comp pistons. And legend has it that after July 2006 a lot of the NA motors got the same rods as the turbo motors, a lot of the later NA motors are used to make 600+ wheel HP with aftermarket oil pump gears and valve springs
Awesome ep. Slight correction on the trans issue however, you can buy multiple bellhousings to suit th400, powerglide, c4 etc. you can cut off the oem bell and bolt the conversion bell to the pump bolts. Companies like Circle D also offer drop in converter options state side. Also we’ve never seen any issued with oil pooling in the cylinder heads. RB’s however suffer massively from oil pooling
Good to know. Appreciate the expert response.
I'm very surprised they don't have head draining issues. Good to hear.

Had two 4.2s, after driving 4.3 Vortecs for a while. Great engines, never ever used any oil, gas mileage was always consistent, power was on point and excellent.

Yep. They just go and go and go and go!
It’s too bad that GM never made a sports car with the 4200 Vortec. It would have been really cool to see in a Pontiac or something like that. I’d imagine it would rival the other 6-cylinder sports cars at the time and possibly give the LS engines a run for their money. This engine could have saved Pontiac. But sadly it wasn’t meant to be.
That's an excellent point , especially surprising considering Pontiac had the 3.8 supercharged V6 they used in the Pontiac GTP... they could have put a Supercharged 4.2 in the Camero or reinroduced the ' sport coupe or a 5 Dr. wagon, similar to the Dodge Magnum Hemi..
GM wouldn't do anything to take sales away from the Corvette
@@markfairhall3671 But Corvette is not for all...... its is not El Cheapo anymore. So they could have done it anyway.
That Solstice Pontiac MG style sports car would've been cool!
What about engine management systems/ support like a Holley or Motec ect. You didn’t talk about that
GM has been using the same bell housing pattern on 90° V6 and V8s for almost 70 years.
As a huge fan of the Barra, I am totally chuffed to know about the 4200 here in the states. As you said, I can see a lot of interest in this engine developing. I get so bored with the same old SBC builds over and over. BTW, has anyone tried to carb one of these? Look awesome with 3 Webers!

Both are great engines, the 4200 probably would've done well in australia as we seem to love 6cylinders and big turbo's
A few things to add RIPSS that 2200hp barra that still runs a stock head with minimal work. so breathability definitly isnt a issue and to add it still uses the factory oil drain setup (car is setup to be daily driven) it doesnt suffer the same fate as the RB platform
Transmission situation isn't as hard as you put it, its quite easy. plenty of places sell adapter plates or complete bellhousings that'll pretty much to go any transmission, i bought a th400 bellhousing not long ago for $150usd.
Oil pump is really only an issue if you plan or sitting at high RPM or bouncing off the limiter, we have plenty of 600-800hp cars still using factory gears (which im not a fan of but they still do it)
There has been a few guys making 1000-1100whp on the Gas rods, (im still skeptical but they have dyno footage to prove it)
I seen a comment about Flexplate bolts ( stop using stock or shit bolts). a nice set of ARP bolts on a nice flexplate solved any issues.
Lol we don't need it tbh, for anything above 4L we have the Nissan tb48 👌 capable of absolutely stupid hp lol
Since the front axle goes throught the 4200s oil pan on 4x4 models, would it be possible to mount it backwards in the back of a car as a mid-rear engine? Or would that cause some oiling issues if its facing backwards?
None of the bolts would line up unfortunately.
@@Calvin-Nelson I don't mean just the oil pan, I was thinking of having the whole engine facing backwards in the back of a hatchback or something with a trans and transfer case in front of it and driving the rear wheels with what would have been the front diff. I'm just wondering if there would be any issues with oil getting thrown to the front of the engine under acceleration.
Thanks for replying.
I really enjoy watching something different at the starting line, racing what you have. It's crazy what those guys down under are getting out of 4 liters. There's an ancient saying; "That to finish first you, first have to finish". That 4.2 sure fits the bill, 800 hp with a bone stock bottom, pull after pull, wow.

If you spend enough you can get a tonne of power out of the Barra. There is a video of an orange Falcon that did 2200hp at a Summernats meet. The green top was an LPG engine with strengthened valve sleeves.
@Barra1385 That is the very same car. It has brutal horsepower.
Questions
What type of valve materials?
Stock exhaust intake flow @.5 and max valve lift
Camshaft options
Stock and aftermarket compression ratio
Long block weight
Probably easier to just give you this. Everything except the valve material is there (not sure what it is).

Theres 3 variations of the "red top" engine. From 2002 to 6-2006 they had thin garbags rods. After that they had bigger rods and 10-2008 they released the engine with stainless steel valves for the new body shape FG falcon. Late model FG turbo barra or late FPV "blue top" barras are the best
In Aus Its basic finance. A barra will give you more HP per dollar than any other engine available to us. There is A LOT of 6-800hp barras on the road that do the school and shopping run during the week and then chop big dollar V8's at the drags on the weekends. And If you break it there is a miriad of spares both new and used available.
I totally get it. For us, it's the LS.
The grey and early green top has what you would call 1r23 rods which are the na rods, then the later green tops and the turbo rods have 3r23 rods and they are substantially bigger. The difference between the two 3r23 rods is the turbo engines have a fully floating wrist pin and the lpg and na engines have a press fit pin
Yep. Good to know. I don't think what I said in the video was inaccurate.
Ok, Ford Australia used to offer the Falcon with a 302, but the 302 did not make big HP, they had been quietly working on the 6 cylinder engines and found they could more than match V8, the name Barra comes from the Barramunda fish, the Barra is a relation of its predecessor the Intech SOHC!! i know there is a Barra in Australia 1200HP!! Never heard of the other engine.
Had a 06 Trailblazer and have to say the engine was silky smooth and delivered power pretty well. The 4sp auto tranny didn't help much for great power delivery but it could get out of its own way when prodded.😊
Im australian, me and my brother who has a dyno shop bought a falcon with the NA barra 6. Has 350000kms on the clock. Didnt change any internals or even the oil or fuel lol. It went from 206rwhp to 306rwhp with 7 psi boost. To me that is very very impressive. Had a commodore with an GM L67 in it (supercharged 3.8L V6) running 8 psi and it made less than 200hp (they were 165kw at flywheel from memory)
Yep. The 3800 is not great unless you throw a bunch of boost at it. DOHC is almost incomparable to an old pushrod engine like that.
@@Calvin-Nelson yeah i get that and the fact one is 12 valve and the other 24 valve still its an amazing difference between engines of similar size.
An Atlas will probably be my next build
Want to try running one in x275 for the weight break
Nice!! That will be very cool
Idk man that’s a tall order for a 4200 block even with the weight break you would have to make 1900+whp to run in the middle of the pack and the front runners in the class are making 2400+! I would try ultra street with one first but even then it’s not gonna be easy and then your gonna need a 150,000 dollar roller with carbon and titanium everything it would be badass combo though!
@@JWoody1990 Maybe the fellow has the actual ability, experience, skills to fabricate the necessary frame ?!
😂
@@CoyoteFTW 😞
What is the biggest cubic inches you could get out of the 4200?
GM built a 5.0L to race in the Baja 1000. With some custom sleeves, I'm sure you could go crazy.
@@Calvin-Nelson would be interesting to see what an offset cut crank to increase stroke would do
@@2HacksGarage I wouldn't want anymore stroke. 4.06 is enough
Although we have a love for hot 6s in Aus ,v8s are just as popular here lol
We had a huge v8 obsession all the way up to the late 90s which is still alive today 👌
A lot of U.S. ls guys are using Aussie ls parts like plazmaman, pwr, haltec etc.
Great comparison between the 2 engines though 👍
Good points on the ease of getting parts staying with locally available engines.
I wouldn't use a 4.2 when the barra is readily available and cheap 👍
Actually buying a fg falcon xr6 turbo myself shortly (2008-2015) for my new daily/weekend fun car, going for 500whp which is plenty in a street car, can run on pump 98 (your 95) and will still maintain reliability 👌
We're not only kings at barras but Nissan rbs and rotory's too 👌🤣
I love what you guys are doing with all the platforms. All I meant by the V8 statement, is V8 stuff is way more common over here. We got the truck LS stuff, so it makes it a natural choice.
The RB stuff you guys have developed is awe inspiring
Have been with the old one from the big three 250 chevy, 300 Ford, 258 AMC, but LOVE The BARRA. Never got one and never will ......
The comparison was outstanding and I did not know about the 4200 Vortec from before, but the Pontiac overhead cam inline 6 was a brilliant in its time. Thanks for all the good info, just amazing know how......
What's the cost per hp to build a 4200 vs, say, an LS?
I would say about 50% to 100% more. LS engines are hard to beat in the States
@@Calvin-Nelson there's just something about an inline six though. I had a handful of jeeps with the 4.0 and miss the feeling.
Small correction about the Barra's availability - It was also the engine dropped in to the Ford Territory, which was a mid sized SUV available in RWD and AWD, and with Turbo fed variants.
The Territory is probably unknown in the US, bloody brilliant car when released, but suffered from Ford US controlling the corporate budgets, and deciding the Ford Everest, made in a country where Ford could underpay workers, was cheaper to import to Australia then it was to build the Territory. The biggest travesty is that the Aussie made SUV was not allowed by Ford US to be built or exported to LHD countries, same as the internal embargo placed on the Aussie Falcon at the very same time that GM was doing LHD Commodores to send to the US as Pontiac G8's. If you lot had gotten the BA and FG series, you would have been shocked at the ride and handling performance, let alone the FPV F6 spec cars.
One of the reasons Ford US spat the dummy over the Falcon's and Territory's, was because Aussie buyers had soundly rejected the FWD Taurus, which was pitched as a new luxury model priced above the Falcon, but was of such shitty build quality, ride and handling that no one that drove it wanted to buy it, when Ford US had decided to try drop the Falcon's in the late 90's, and replace them with RHD imports.
Ford Taurus, a friend had as a company car i drove and it was unfun. lots of comfort tech but ugly and a shitty drive.
1998 I hired a FORD Taurus in LA drove to Las Vegas via death valley and to Grand canyon and back to LA.
It was a far better car than the RHD shit boX Ford sent to Australia.
The 4200 is so under rated and under appreciated. Really is the best bang for the buck in terms of capability and performance.
Yep. For sure.
And reliability!
and lets it stay that way. hate taxes, like jdm tax shit
@@stiligru8468I'm with ya on that jdm will break the bank
I wanted a Barra after watching the Aussies. But now you make me want a 4200. This coming from someone who has a few Coyotes (and a few GM "LS" swaps).
As for stock potential power the Barra was competing in a market were fuel consumption was a bigger deal were the Atlas was competing against V8s so the rods was one place the Ford engineer's could save some weight. Keep up the 4200 videos 👍🇭🇲
well that is one place the barra loses out awfully, fuel economy or lack of it mine loves its petrol
@@victor22366mine is great one gas and I trash it every day
Ba falcon series 1 engine had the weak conrods stock, bf series 2 conrods and onwards were improved significantly. I've seen figures of 700hp with nothing but boost and valve springs
VERY glad you made this. There is not a good unbiased review online that i could find. Doing gods work- you are a pioneer in the journey of the aftermarket swap world of 4200s
For those talking about the flex plate bolts; yes they do have a habit of backing out, got nothing to do with how many bolts it’s to do with the thickness of the flex plate, it’s thin so clamping force and vibration are the problem,usualy after market thicker flex plate or a simple bolt locking ring will fix it,been there done that,and for some a little weld on the bolts but not really recommended
Epic. Can't wait to see how things progress further. However, I also want more focus on the 5-cylinder Atlas since that'll actually fit in my application. That, and a 90mm de-stroke crank (for both) if possible. IMO 90mm is the best stroke for a street car, 8000rpm capable at only 24 m/s piston speed. The ultimate goat would be if all of that was doable ON TOP of a diesel conversion, but that's because I'm too much of a min-maxer trying to have my cake (fuel economy) and eat it too (power).
Destroked 4200 crank would be sick. Same for the 5, but I'd be more stoked for the 6
I had the 4 cylinder version for a while (2.8L) and it was an amazing engine! Great power output and great fuel economy too.
There's a work truck tax on the 4/5 cyl Atlas so they're less attractive compared to GM car engines like Ecotecs and V6 options that make more power at less weight/size/cost.
@@mattbirt114 now that's interesting. Seems to be completely different from how it works over here in Germany. A truck registration for a car can save you some car tax money. The specific engine type doesn't matter. So, for example, one may get a truck registration for a VW rabbit by taking out the rear passenger seats and removing the rear seat mounts to make a transporter out of it, this will save tax money for the exact same engine.
@@nopadelik9286 Lol German literal English interpretation moment. Ok, it's not an actual tax on the used engine. They just cost more than they should, like 10x what a 4200 costs ($3000 vs $300).
Both ford and gm don't make them any more so what's modern equivalent? BMW, Mazda, or Stellantis??? Mopar is selling Stellantis crate engines in different hp outputs ...
Seems like the Dodge or BMW are great alternatives. We will see!
Have you considered building a "I've been telling you guys!" 4200 for a little head to head dyno competition with some of the aussie guys? That could make some good headway on attention to the platform! I've been really impressed with the 4200's capabilities. An it IS a shame you don't see more builds out there.
Hope all is well with you an yours. Take care 👍
I was hoping we could line up at Sick Week this year. That didn't go to plan. We'll do our thing and see what comes along.
this is my plan for my 77 gmc. time to plan, budget, find all the goodies and figure out the wiring system
Heck yeah!! Do it do it do it!!
Was looking forward to this video and your opinions on the pros and cons between both, great video!
Thanks so much!
I killed a 4200 by driving it for a month with no oil, it finally let go when I redlined it. I was going 40k miles between oil changes until it died at 200k
The LS V8 actually was available as early as 2003 in the GMT360 / 70 (Buick Rainier, and long wheel base versions of the Isuzu Ascender, Trailblazer, and GMC Envoy) platform as a 5.3 until the Trailblazer SS came out in later years. I have an 03 Envoy XL with the 5.3 but I originally wanted one with the 4200 until I figured out there wasn't really any performance aftermarket support for it.
Wish GM would have stuck with the original TBSS concept, the turbo 4.2 making 400hp. If they had then there would have been a ton of aftermarket support available
it was extremly rare but some swb trailblazers had 5.3s
I'm a Aussie so that 100% makes it only a Barra for me.
I'm currently collecting parts to build a 67/68 Mustang for Barra power. I have a early XF 1990 ute im using the T5 from.
Can use the 1990 to 2001 OHC 6 T5 bellhousing to adapt a earlier T5 so the shifter is in the right place
I could fit a Windsor but as I "Only" want 400hp a almost free Barra is the cheapest and simplest option
Grey top, standard computer with smart lock removed and locally available factory wiring harness modified for 3 wire connection.
Sick!! Hope it makes you super happy! Do you happen to know if the Barra matches any of the common Ford platforms?
@@Calvin-Nelson no, it’s unique, basically we had the 200 log head a direct copy of the USA 200, became a 221 for XT Falcon in 1968. From then to the Falcon Crossflow steel and alloy head right through to the end of the pushrod Falcon 250 in 1990 was the same bell housing pattern as the mid 1960 USA engines. (There was a 3 or so years when both push rod cross flow and SOHC 4 litre was made by Ford Australia)
When the EA Falcon came out in the late 1980s with its SOHC engine, it came out with a new bigger bell housing pattern that was used right to the end of the Barra production.
There might be variations of bell with thread sizes and dowel placement but my understanding is it’s the same 1988 to 2017
@@Calvin-Nelsonthere is a lot of support to run gm automatics, and they also run the ford c4 autos, the btr 4 speed they come out with are very terrible, they also offered them with a zf 6 speed derived from the European BMW's, jaguar and others that ran that, in manual trans they where offered with the t5z, t56 and tr6060 in the fpv models, so there is quite a lot of options
Thank you for all this awesome info and all the work you put into the channel!
yes, ever since i found your older videos making the Atlas a power house and been closely following cuz im oogling a trailblazer that blew her headgasket and has been sitting after that... this just gives me hopes that support ramps up and lowers prices so it becomes accessable to me
I lost the shop.
Oh no! You had better throw a chair through a window and leave the shop doing a burnout through the parking lot, the grass, the shop, and hell get up on the roof with it as well! Then sit down and tell us how everyone was against you from the beginning. 😂
246K on my stock Trailblazer 4.2 and it has the original trans. I did change the trans oil and filter once. Sometimes I suck about 4 quarts out through the dipstick tube and then add fresh oil. Just changed motor mounts, valve cover gaskets, intake manifold gaskets, front brake rotors and pads, front wheel bearings, and rear brake pads. Out of frustration, I ripped out the module that changes from defrost to floor to dash and threw it in the yard. So, it now only blows from the dash vents. Now, I need to change the temperature blend door actuators and I'll be good. LOL. Changed a lot of front-end parts and motor mounts throughout the years. In my opinion, the Trailblazer 4.2 is one of the best vehicles ever made, apart from a 1962 C10.
I always felt like the Ford 6.2L (offered in the super duty, 1st gen Raptor) is gonna be like these inline 6’s. Great performance capable engines just not recognized until later.
slap a 2.9L whipple on top and you can make upwards of 700
The LS sumps are a structural part of bottom end also -- other sumps made from steel are also used in aftermarket conversions - Barra too..
It sucks they stopped making the Barra’s and the 4200’s both are such amazing engines
I have a 06 Trailblazer EXT with a 07 engine, son blew up original. Thought this 4.2 would be nice in a late 50's-early 60's Jag sedan, but I have been seriously thinking about putting whole frame and electronics under a 41 Ford Super Deluxe sitting in my drive way I think I saw you in the Nova a couple years ago. Fantastic what you have done with this platform.
Funny that you made this comment. Ive been in the process of putting a 4200 in my 55 Jaguar Mark VII. Fits like a glove so far. Still working on getting it running.
That was very interesting and informative! I've been thinking about trying to build a /6 mopar engine. Of course I will definitely need someone who actually knows what they're doing to help guide me but I've seen a few pretty quick ones and I always thought that it would be cool to run one in something like a little Plymouth Arrow. Great Video!
Thanks! I love the old schools 6s I fully support the slant 6 build.
Yo dude good try but bathurst 1000 is a v8 race between ford and holden its huge and the reason why they stopped producing the falcon xr8 was because the barra turbo was just flogging everything out of the water and the barras where also found in the territory. Im 2 min into the vid mate.
Other then that the rest was pretty spot on with the barra i wont comment on the 4200 not my area
Staggering amount of information in this video. Doing the lords work!
It's a shame Holden didn't use the vortec 4200 in the commodore that would have made for some interesting competition between the two especially if they made a turbo version.
Both WAY better than a small block v-8 or Japanese I6. Amera Barra Haters "Imitation is the highest form of flattery" These engines are both incredible with factory blocks. If the crank journal sizes are close enough( I am guessing based on my engine building experience) you could potentially use the slightly longer Barra rods in the 4200 along with some .025 overbore Barra pistons. Wrist pin height vs block deck height being the main concern.
Yeaaaa caus you never see RB26s making 800-1000 hp and holding together or even 2JZs for that matter 🙄
@@alexinnewwest1860 The amount it takes to get them there is.... EVERYTHING. So yes they exist but no I don't personally believe the small block are better than the big blocks. Use to run LS engines in my rail on alcohol and would use up between 2-3 a season. Switched to a 454 based block in 2017 and have only rebuilt it 3x's. No broken cranks or blocks. My point being yes the smaller engines can make the big dyno numbers but their not going to live as long at those extreme levels of cylinder pressure as well as a larger displacement engine with more material to spread the abuse across. The crank main, and rod journals are quiet a bit larger on the US engines as well as the block and head bolts...... The Japanese engine I have mad respect for but STILL NO REPLACEMENT FOR DISPLACEMENT.
Hmm, Coyote Gen III or truck 5.0 (different firing order) are good to 1000hp. No knock on I6, a fan but “way better”?
@@ProjectFairmont Love a v-8 as much as the next guy but here are the facts like em or not. Basic I-6 Architecture dictates if all things are equal the I-6 will have more power and durability per/L. I-6 has 120 degrees of crank rotation to apply power on the power stroke. V-8 has only 90 degrees. I-6 has only 1 connecting rod per crank journal, all V engines share crank journals. More main journals per cylinder ie. i-6 has 7 mains for 6 cylinders when counting end journals a V-8 only has 5 mains when counted the same way. IN addition A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. These are mathematical principals that transfer to engineering advantages. So yes WAY BETTER. These are the reasons over the road diesel in big rigs were rarely V-8's. Nearly all I-6's.
@@playanddisplay3636 like I said, a fan. Nothing you said I don’t already know, god bless ‘em. However, to say way better than V8? First of all early I6s did not have cross flow heads, is that a deal breaker, maybe maybe not. Fact remained it took more work to make ‘em work than a small block V8 cause they were smaller in displacement and couldn’t rev without major flow work. The Ford 300 is a long lump of an engine to go racing in a car. There is a huge gap between those anvil tough but crude sixes of the 50/60/70s and the Barra we never got (based on the OG US Falcon six) and the 4200. Filled kinda, by the 2JZ, and BMWs mostly. But still not critical mass. V8’s on the other hand have steadily improved and offer bang for the buck by virtue of availability, aftermarket support and basic robust qualities. Now if I was in OZ or NZ I would be all over the Barra haha!
Love both engines. The Barra's issue is logistics, and transmission issues. The 4200 is aftermarket support. Would that 4200 fit in my 49 Studebaker pickup?
Yep. Totally agree. Yeah. Should fit good in that.
@@Calvin-Nelson
Great, when can you swing by and get it?
I hope some company further invests in the 4200 in the future, to the point of CNC-machining blocks and heads and 3D-printing whatever else is required. It surely deserves.
I wonder how much of this info can be applied to the 3.7
I5 bore and stroke on paper are identical. Love the baby V10 sound of a I5
I think a whole lot of it could be transferred.
@Calvin-Nelson I think the only issue would be the balance shafts with the i5 am I correct? You could put forged internals in it, but without the balance, it would just shake itself apart.

Mate as an Aussie and a supercharged Coyote owner that’s all ex factory your Barra assessment is fair in relation to zones, and availability well and truly ; check out engine power on their slant 6 build and having to source inlet manifold and stud girdle/ rocker set up from Australia hence the wait before doing let alone filming build
Very cool video! I knew some about these engines but that was really interesting to see all that info. I'm personally a huge fan of the Ford 300. I'm so happy seeing people trying to fit in LS heads to them nowadays. I am not sure I've seen a successful street version yet, but still awesome. Hopefully the Dodge/ Chrysler/ Fiat/stellantis new inline 6 will be able to be added to the mix in the future when we can start grabbing them up in junk yards. Hopefully they fit yhem to a lot of vehicles so they'll be easier and cheaper to get.
I like your positivity. You're my type of dude! I'm looking forward to seeing the Hurricane develop too.
As an Aussie, ive fpund your channel and particularly the info on the 4200 fascinating. Nice comparison.
Hey Calvin. Great video. Really informative. I assume the lower frontal area of an I6 compared to a V8 might make it attractive for some speed records. Has anyone taken the Vortec to Bonneville?
And when can we expect to see you competing with the Stude? 😁
yes. The Vortec 4200 holds a couple records at Bonneville actually.
Almost done with break in on the Stude, so probably 2-3 weeks you should see a video.
Did either engine come stock with a turbo?
They did not, but GM experimented with turbos in the development of the engine.

Being dumb is not cool Steve.
I have a 2002 BA turbo sedan which is one of the very first turbo barras made, it's had mild mods and a tune (using sct's Xcal3) and makes 290Rwkw or close to 400hp at the tires on a rolling road chassis dyno. Has been that way for over 11 years now and is still reliable as. No replacement oil gears in the motor (as claimed required at 5.59 in vid) or head studs etc, just upgraded valve springs so not sure why you'd be needing to do oil gears on a mild motor. Also guys in Aus have boosted the grey top "weak" internal engine to over 420Rwkw (563HP @ tires). Alos have a 2003 BA Turbo ute making same power with same mods as the sedan, only thing thats really failed with both has been the BTR 4 speed auto when in stock form, rebuilt and beefed up a little they have performed well. The main rule to longevity is all in the tune.
That's great man! I'm just going off what I've read on the internet and seen in videos. Hard to know all the facts when I'm not immersed in it. I think I got most of the major stuff correct. Sorry I missed a few of the minor items.
4200s can go 600+ whp (450+rwkw) without touching anything. (No valve springs, or oil pump gears) you can also hang out on the rev limiter no problem too.
@@Calvin-Nelson The reason I mentioned the valve springs was relative to my 2 BA's as they had the weaker springs which were upgraded in BF on models. In BA they would get valve float from as little as 10psi where as BF/FG/FGX will go 15psi on stock springs. Plenty of skid kids getting into NA barras around the place and they seem happy sitting on the rev limiter as stock engines, sure going more than mild oil gears would be good insurance but as said, in stock form, skidders are popping tires and blowing diffs left right and centre with the engine bouncing off the limiter yet holding up fine. All good for the 4200s for you guys there as you correctly point out they and the Barra are very close in most areas and clearly both good 6's. At the end of the day you use what you can access easily.
I'm confused how the 4.2 doesn't bolt directly up to the same transmissions as the LS when they have been used in the same applications interchangeably... Did they have different transmissions for the same cars based on if they were LS or Atlas engines?
They had a removable bellhousing, and LS got one, Atlas got the other. It really isn't hard to adapt.
woah woah woah @19:38 where do I find more information or videos about pfi speed and the design of that engine? I am so curious!
It's all been lost to history.
