Ran into this video again, and still impressed. 😂. Stock powdered metal rods, stock cast pistons- most likely with factory ring gaps, stock heads, and stock exhaust manifolds. Throw a moderate cam into the mix, a generic centrifugal compressor, and no intercooling, and it lays down comparable power to the Ford Raptor’s Ecoboost... with only one camshaft, pushrods, and a carburetor too. 🧂🧂🧂
Very true. Going on 12 years.. I’ve raced everybody willing to run off red lights. Hammered through swamps in 4 low. Gooning down dirt roads like I’m Ken block. And even jumped it like the duke boys. The 4.3 is an absolute STUD. Little gutless. Just enough oomph to have fun..but a STUD. General maintenance and a couple fuel pumps is all it’s asked for. Creeping up on 300k miles and it’s just happy as can be.
@murdyg7382 I had one in a boat. Broke a belt and overheated it till it seized. Replaced the belt and rode it like that the rest of the summer. When I pulled it apart in the fall, it had 2 blown head gaskets and there was a spark plug tip bouncing around in one cylinder. Thing just wouldn't give up.
This is fact I only just have my license. 16/17 years old growing up in Newfoundland my father had a 95. What a 4.3 and a 1/2 ton he used it as a worktruck. He was a mechanic welder. We hauled wood with it, but when I got my hands-on it. I was literally just hammer on it and hammer on it and hammer on it. Laid rubber everywhere. Yes, we did lose a transmission, but Hey, it was still going at over 500000 km before he sold it. That engine is a representation of what GM could do.
I love the 4.3L engine, it's a little workhorse! I have a '95 Chevy 1500 single cab w/ a 4.3L. I use it all the time towing vehicles with a metal car hauler between Texas and Missouri. Does great going up them steep hills with the a/c and cruise control on. Vehicle never strains and never slows down with cruise control on. I have two fairly low mileage stock turbos off of two different Subarus(Sti) that I been waiting to use on the 4.3L. Guess it's the perfect time to do it, since time is all I got now lol. Thanks for all your hard work on all these videos! 👍🏼👍🏼
@ihategooglespooks Yes I've been to Texas, and Oklahoma. 3% grade for 1.5 miles isn't much. Even a 5% for 1 mile. You've obviously never been west, 5-7% grades for 15-20 miles.
@@johncholmes643 How is my statement contradictory? The highways are not flat all the way there and back. Just cause something isn't as much or the most isn't contradictory. I wasn't even comparing grades of different highways. I have driven my fair share in Nevada and California. Seen the runaway truck ramps. My statement was a testament to the 4.3L engine, if even for 1.5 miles(actually further), which is more than enough distance and time to get results. I find it interesting in your other statement that you been to Texas and Oklahoma, but didn't mention Missouri. Sounds contradictory.
@@Second-gear Back when I was Tractor Pulling for money, I showed up in Kentucky. An old boy pulled in with a 6.9 Ford F250 pulling a 42' enclosed trailer. Just not used to the flat lands of of that country.... it certainly is different.
Same here. Since the 4.3 is based on the SBC, you can use a bunch of SBC parts (rods, pistons, valvetrain components, timing sets, water pumps, etc). But there isn't much available for heads and intake.
If you like V6 motors, find a 3.6 dohc GM LFX. LGZ....... ITS a LS 6- BOLT mains with oil squirters, poly bearings, coated pistons...you name it!!! All 4 cams are vvt full-time!!!! Direct inject. Forged Crank!!! And they fly!!!
@@BlackFyreGroup its the one used in the Cadillac camaro and i think the colorado and canyon minitrucks. They have made a ton of them and they are kinda popular for miata swaps as well.
There was a brodix 23° v6 head for a while but it wasnt really a street part and was really expensive. A couple guys use to push them really hard in race classes that had lb/ci limits and do pretty good. The things that make them good also killed the aftermarket, a v8 almost always fits.
I had a 93 Typhoon in the early 2000's and i was blowing doors off of t/a's, mustangs and camrro ss. It was a stop light warrior w 350hp and 415 lbs torque.
Gm brought a couple of Typhoons and Syclones to Detroit Drag-way in late summer of 1990, before they went on sale, they were ripping off low 12's like they were nothing at a bumpy, slippery track. I remember the Gm employees driving them saying, these were TWEAKED a bit, but production versions should hit easy high 13, with very little TWEAKING! I also remember them saying GN drivers wont F with these when they hit the street. I have a 88 s-10 Blazer, (20 years) but I still want one of those.
It made them decent. They were good in cold weather and only if you got a good launch under boost. It took 13-14psi of boost to make 280ish hp. That really isn't impressive. It was only impressive for that time.
@@frigglebiscuit7484 look on YT for the father-sin that built a S10blazer turbo AWD FLYING MILE speed was Unreal!!! OEM tx case. AWD can be a Huge advantage. GN 3.8 responded VERY WELL to simple mods & EEPROM CAL!!! GNX is a rare bird, and only a Krazeee person would mess one up! I worked with McLaren engr doing the GNX motor. Hand ported 3.0 head, ceramic turbo, and who knows what else they did internally! GNX is an incredibly rare collectible.
Richard Holdener if your question was to me, yes. Though your channel is geared towards v8s (as it should be), I would enjoy seeing a knowledgeable engine builder throw some internals and a big turbo at a b series or k series Honda engine.
@@youtubeisbroken241 Richard has stated in previous videos that he has plenty of experience with Honda 4 cylinders. Keep in mind he's been at this for a long time so he's been through many "trends". I suspect a future Ford Godzilla trend. I love LS engines and anything that's well designed and makes power for that matter but that new Ford big block looks like it's gonna be a game changer.
richard.this series is a gold mine of info for us older gearheads from the past,who allways wondered "what if..."many of us have no interest about what has been coming out of detroit over the last 2 to 3 decades.thanks for representing us common working men who also wonder "what if...?"
I actually tuned one on a chassis dyno back in 2014. It was in an O3 S10 with a 5-speed and factory port injection. Mods were: cam, long tubes and a centrifugal supercharger on 10 PSI. It made 350 hp at the wheels on a mustang dyno. Factoring in a 15% driveline loss that puts crank power at about 410. Since you run yours without accessories, made 3 more psi, ETC, that roughly puts them on the same plane.
Sounds like the kit on my truck, hangs around 10-11psi once it's fully rolling. With the 4l60 it's best time is a 12.9 so I'd guess in the range power wise of where you're dynoing.
Just ran across this guy's channel because of the 4.3 turbocharged and figured I'd throw in my two cents I've had a few of the s10s and blazers just lost my one owner ZR2 that was special ordered as a five-speed in a fire.... 😞 I love that Blazer probably never find another one like it that's that clean anyway the clutch went out on me so I did some research while I had it apart and decided to do some testing the stock 4.3 flywheels for the five speed are ridiculous heavy best I can remember it's 44 lb and just so happens the flywheel for a five-speed 350 vortec only weighs like 11 lb other than that they're almost identical so I decided to try it and was amazed at how much better it ran how much more responsive it was with the throttle and how much better it drove and shifted couldn't find a lot of info on it so figured I'd put it out here on this in case anyone else has ever thought about it I'll do it to every single one I have from here on out LOL
This would be completely crazy in a little Vega sleeper, stock wheels with Turbo 350, 8.8 rear end with 3.73 and disc brakes from an Explorer. Complete super SLEEPER!!
I've been wanting to see an "Other Guys" kinda show for a long time. I'm tired of every show being about an LS, or a SBC, or a Chevy, Ford, or Dodge crate motor. I'd love to see the creativity of older engines with modern technology thrown at them. Thank you!
Thank you! My favorite vid so far. I’ve moded my 98’ Blazer’s 4.3 with a comp cams 266HR cam, ground off the teeth of the balance shaft, trick flow chromoly push rods, comp cams pro magnum roller rockers 1.52, minor head port/gasket match, HP Tuner Suite. Surprised how much power you got. You Sir have my subscription!
400M was one of my favorite engines. They were a dime a dozen, always 2bbl, seldom ever abused because they didn't make any power.. basically they were a tall deck/long rod Cleveland. Thanks for the vids man!
Jon Kasse used them to beat everyone into submission in the engine masters challenge. Granted he is a wizard, there is something oddly romatic about an engine out of a lincoln taking top prize.
I snagged a 351 Cleveland for 800 bucks with an entire f150 attached to it lol. Even though it was old and worn out it still hauled ass but it needs a rebuild so idk if I wanna keep it and rebuild it or just part the truck out.
i look forward to seeing testing on the more uncommonly built engines, I think they are more interesting. A Ford 300 straight 6 would be a cool one to build, there are a ton of them and there is decent aftermarket support.
Really like this video, there’s not a lot of people doing much with the 4.3 V6 Vortec. Usually everyone on forums tells you it’s junk. This test proves it’s not. In fact After I’ve ls swapped my s10 I’m now going to keep hold of the v6 vortec motor and do a separate build with it. There is also a inlet manifold kit that allows you to run injectors (not spider injection system). Can wait for more videos on the 4.3 v6. Peace from 🇬🇧.
After years of getting made fun of back in high school for having a 4.3, the only engine I have nowadays are v8’s. But I still secretly love the 4.3 for how much of a workhorse that little engine was!!
I've seen plenty of hot rods and projects built on the 4.3L V-6. I think is is worthwhile. For many, 400 - 500 HP is fun but not out of control in their vehicles. I would think folks will use these more and more. I'd even love to see you tackle an inline 6. Great video as always.
Hey Richard, great project and awesome results! I think the torque storm supercharger is far easier and cheaper upgrade, than a LS swap. God for give me, for saying that. But I really think this video opened people eyes, to the potential of this combination.
Thank you for doing it. I have been getting a lot of crap for the same idea. You validated a lot of ideas I already had thank you for doing the legwork and sharing.
I wanna see the 400 under single turbo boost. There's a lot of guys/gals out there that don't want to have to swap in a 460 and a 400 under boost would be the ticket.
I personally would like to see you do a video and build of a 60 degree V6 such as a 2 .8 173 cid chevy v6 i think that would be cool and i think a lot of people would be really surprised at the torque and horsepower these little motors can actually make.
I have an 85 GMC 1500 that’s got the 4.3 in it with 170K and still runs. These engines will last if you take care of them. Extremely simple an reliable.
I'm definitely one of the other guys. I ran the 4.3L V6 for my Typhoon on the dyno (minus turbo) to break it in. It made 276hp & 306lb-ft of torque thru stock n/a manifolds and Y-pipe with an untuned 850cfm carb sitting a top 3 inches of carb spacers (to get the carb linkage over the fuel rails) while running 91 octane from the mom & pop gas station from down the street. It was built to handle 30psi AND a 100 shot of nitrous. Currently I'm running the stock turbo & boost (14.7psi) as I'm sure the stock 700R4 won't handle the 1st AWD boost launch I do but I can't wait to stick a bigger turbo on & turn up the boost once I finish the 4L80E swap.
The 4L E 80 is a butter trans than the 700 R4? If so that is good to know I have a 4LEDA and my S 10 and was thinking about swapping it out for a 700 are for if I get a 350 or 383 stroker crate motor thanks for giving me the heads up very appreciated
I have an 85 cutty and was thinking about a 99 4.3l vortec for a swap. Thanks for the light, bruh. Your show is major informative and saves time and money.
Suggestion for The Other Guy candidates: Late model Chrysler LA engines, specifically the Magnum 5.2L and 5.9L. In my area those a dirt cheap because people are convinced that they're terrible engines that can't make any power, I think those people are wrong.
Ok big chevy and mopar guy here that 5.2 on 12psi is a total animal. All did to it was a mild cam swap and then a tt setup and my 79 dodge is making 680hp to the wheels. I probably should have gapped the rings but the motor had 170k on it and i didnt want to bother with it.
The magnum 5.9 is easily the best bang for your buck as a direct swap for any mopar that came before it. I import them to Australia coz it's still better value than reconditioning a 40yr old LA360. The disrespect they get is huge. I've had people literally tell me it's not even possible to make 400hp from a 5.9. Also they make pushrod oiled shaft mounted rocker arms to allow a retrofit of LA style cylinder heads onto a magnum short motor now, so the "bad flowing magnum heads" is no longer such a big deal breaker for high hp builds.
And I agree I knew a guy that had a cam only Dakota rt back n the day and it was decent he did heads and Intake then the truck was totaled and he kept the engine and maid it a stroker and swapped it into a regular cab short bed Dakota with the insurance money lol
They only blow up when people do not maintain them. I had Crane 218/224s, 08 manifold, and headers on my 03 Dakota. Used to spin it to 7,000 rpm almost daily. Mobil One 0w40 and Mobil One filter every 5K. Truck is still going strong. My brother still has it.
@@konnerkramer329 i have a 4.7l in my jeep GC fully ported heads no cats ,exhaust, and custom built CAI, and it get down pretty good and has over 340k miles on it and doesnt burn a drop of oil or tick when cold or winter when first started, worst part about them is if they get a lil hot they drop valve seats, they come with factory forged rods and pistons atleast the 02's did in the jeeps, i hung with some turbo honda's with 4 people in my jeep and its all wheel drive so that doesnt help it but wonderful in the florida rain :), i think i took about a solo cup's and half worth of alum out of each head when i ported them and did all the bowl blending, lil chamber softening did all the porting @ 219k miles. They have a really long intake runner in the head and its very restrictive and the exhaust side is very short and not so bad but needs work. I really wanted to turbo it but when i was looking into it i could not find anyone that could tune it, so i didnt get to much further ,maybe now there is someone. i could of did standalone but i wanted it all stock ecm so everything would function normally , also the 4.7 H.O. has about 10.2 comp ratio and the non H.O. has 9.5 but the H.O. has about 16 more degrees of duration and about .020 more lift than non H.O. I still have all my research on doing the twin turbo's for the 4.7l but the jeep GC platform has like no room for that kinda stuff, the pick -up would be better suited for room for twins of a decent single.
@@chrisdeez2176 I'm sure you can make them pretty peppy but do that work to a 318 or a 360 any you'll run rings around a 4.7 all day. Ive never personally messed with the high outputs so I couldn't tell you but I do know the non HOs don't have forged rods and pistons. They're not terrible engines but I don't know why anyone would ever want to build one. I built a $800 355 for my k10 that makes more power than a "High Output" 4.7 does. I know there's an entire liter of displacement difference but my block is a 1968 casting with 1972 993 heads and an RV cam with some .030 over flat tops that came out of a 350 irrigation motor that ran on natural gas... stock crank, rods intake, and carb. And it makes the same top end power and more low end torque than the ho 4.7s with port fuel injection, electric ignition and 2 full points of compression more.
Richard, thanks for all your comparisons and information. You have a knack for posting useful comparisons and shedding light on less documented engines. I found your channel a couple days ago and we must think alike! You have provided facts and data on many combos and parts I have wondered about. Thank you for sharing your hard work, it is greatly appreciated!
This guy is a engine building genius. I love the idea of running a v6, just to be different if nothing else. What a blast it would be to have him on a project right?
Thank you so much!!! I LOVE IT!!!! 500 hp divided by 262 cubic inches equals 1,71. I agree with you. I would love to see more love for the 4.3. An option I am considering as well. Speedway Motors offers ceramic coated shorty headers for the 4.3 as well. A great set of CNC heads would make this a miracle motor!!!! Add a TPI intake and you are gold !!!!
Thanks for the video, same thing goes for the 3.8/4.2 ford ive been out of the game for a while but guys were really pushing boundaries in 2003-2008 with 6-700hp 9 sec et's
Glad to see someone finally do some 4.3 love. There are a zillion of these just rotting away in junkyards. Tough as hell little engine and it's obvious there is power hidden in there.
They are strong ass little motors a lot of people don’t realize it is a 350 minus the back two cylinders just wish there was a decent selection of aftermarket performance parts for the 4.3 L but unfortunately there’s very little to none
As long as you're looking into alternatives, comparing this 4.3 to GM's 60° high value V6s and Buick's 90° V6. Both have aftermarket support and the 60° V6, despite being the smallest both dimensionally and displacement wise, can make astonishing power with a cam and spring change.
The 3.9 v6 that came in Uplander van, Impala etc. from 2008-2012 will make 500 hp with a GT35 turbo and E85. There is an IROC somewhere on youtube running 10.56 with that setup
@@VTLIFE-so4dc that car ran at my local track. It did well in a race series I followed but I haven't seen it out since a few years ago when police were harassing people going to the track.
I built a 4.3 like this about a decade ago, same intake, same cam. Added long tube headers and did mild porting. It made 435 ft lbs and 389 hp. Motor came out of an 02 s10 extreme with 20k on it.
I would like to see what could be done with the Ford 3.7. These engines were placed in Lincolns, Mustangs, and F-150s. These engines can be had cheap, the internals are relatively strong, have some aftermarket support, and can produce good power even at low boost. I have one that 420 rear wheel horsepower on a Mustang dyno at only 9 lbs of boost. I'd like to find out the limits of that engine.
I'll tell you what you can do if you own one in a FWD car or truck: Be on top of your timing chain driven water pump. If it goes out it will take your engine with it. The tell tale(weep) hole leaks coolant INSIDE your precious high tech, high dollar engine. The ones installed in the F-150 apparently have different design.
@@bobhilly546312156332 no the fwd versions have timing chain water pumps. The red f150 mustank idk what else have belt driven. Idk if the blocks can be swapped though.
I love my 96 Chevy c1500 4.3 v6. Just finished rebuilding the engine. Bored 30 over with high compression pistons. Compression is 9to7.1 with thinner head gaskets and running with a computer friendly hydraulic roller lunati 268 276 cam with 503 lift 111 lobe separation. With a Tuned computer. My pickup put down 244 horsepower to the rear wheels and 267 ft of torque. For being all motor. I'm very happy.
I remember when the first of the v6s came out n was impressed back then of the power. Some need to remember that coming out of the years of the gas shortages and smog years late 70s and 80s horsepower was low. Early 80s corvette smallblocks had 180 or so horsepower!
I have a 2002 S-10 that I bought it brand new, and its been my daily driver every since. In June, it will be 19 years that its been my only vehicle. Ive been wanting to do a performance build on it for years, but like you mentioned, there are basically no performance parts available for these engines. Other than camshafts, and headers. I wish so badly that they had performance heads available for them. Because if I build mine, I would want to keep it N/A. Would love to see many more episodes centered around 4.3 performance builds. We S10 guys especially would appreciate it more than you know. Thanks for all this info Brother!
I'd be curious to see the blower results with the stock cam. It was interesting to see the torque curve for the blower run was similar to the aftermarket cam, just moved up the rev range a little.
Stoked to see you doing this engine. I just pulled one out of my ‘02 Silverado that you can have, it’s kind of a turd without boost, and like you said little to no aftermarket support. It has a five speed and leaks from every gasket but I’d donate it to see you boost it to the moon!
I had a 2000 S10 extended cab with the step side bed and the xtreme appearance package. It was a 4.3 auto, I put 4.10 gears in the rear with a locker, the transmission had a corvette servo and a shift kit, and for the engine, electric fans, under drive pulleys and a healthy 150 wet shot of nitrous. That truck was fun to surprise people with. It did have a little suspension work but nothing really special.
The M90 blower is in an of itself kind of a choke point. I'm sure those engines could pump out some impressive numbers if you swapped the M90 for a bigger blower, or a turbo.
Your continuing the work and love of the odd stuff that I read about 30 years ago in "V-6 Performance" by Pat Ganahl. It was actually written in the early 80's when the 4.3L was just coming about, but guys like Grumpy Jenkins were already pushing 450HP from the small block V-6 just to see what it could take. I still pull that book out and look it over from time to time. I originally bought it to research a 60* V-6 engine build I was doing in high school, but was disappointed that the book was written before the advent of the TBI injection I had decided to run.....still a great read and a blast from the past!
@@GIGABACHI balance shaft motors are not good to build for performance period they don't withstand rpm and they don't make a balance shaft delete for these motors
@@GIGABACHI best to get a block pre balance shaft get later model heads then go from their waste of time money and space in my opinion just go to a Nissan vq35 they are easily 300hp only downfall is you can't just slap a intake manifold on and carb and go
I know they are still a bit hard to get in the wreckers but I would love to see a new ecotec3 lv3 v6. They make a ton of power, camshafts are just making it into the pipeline and all the lt1 corvette goodies can make them rock. How you run them they would probably make more than 300hp stock.
@@utahcountypicazospage5412 no, it's the 4.3l v6 that came in full size pickups 2014- it's based on the gen5 push rod architecture. Aluminum block and heads. They make 285hp SAE, like 40hp more than this engine before the blower.
That's great I've been wanting to build the one in my 96 blazer for ever now.. now I know where to start thanks very very much! But I'd love boost so I'd like to see 20psi at peak and probably have cut off at 23-25 psi but I'll get there one day!
Probably very hard to find performance parts for that engine. Would need custom cams cut. One off engine management. It would be cool, but impractical.
Wow that is just mind blowing. I mentioned doing this on another video. He answered me. Lol. Idk. ? Don’t underestimate those v8-2=v6 engines. Great videos
Oh yeah I really wanna see build up of Ford’s 289 and 351 cleveland and sure the 400m too!! As the 400 is basically a tall deck stroker 2v cleveland. 😁 And maybe add the 429/460 to the list too. 😎 Especially I wanna see the Boosted applications! As those engines are pretty common at my ”enviroment” 😀👍🏻 Would be awesome
Thank you for getting out of the box. I had one in my Astro van 4.3 vortex and that engine ran pretty good. I would like to put one in my Jeep for a future build.
jesus, 13.3 psi on a mild build.... Those IAT's... Glad to see the v6's are getting some love. Would be really interesting to see a shoot out between the 3.7 cyclone v6 and chevy's 3.6
Hey Richard, I guess I’m one of the other guys. I have a 292 y block Ford that is going into a 1931 Model A. I’d love to see you do one of these y blocks and see how it goes. Love that everything is dynoed and as they say the proof is in the pudding!!!
How about adding a cam+turbo to a Vortec LL8 and big bang it, see how close it can get to a 2JZ. Jeff Smith wrote about one back in 2011, pushed 470 on 8lbs, curious to see how much was left on the table.
trdscfjc the issue with that though is there aren’t any aftermarket cams, or really anything aftermarket for that matter available for the atlas series engines. That’s why so few people mess with them
I remember someone on SupraForums swaping one into a MKIII supra Using an AR5 Transmission which is basically A toyota R Series Transmission with a GM bellhousing (R154 Is stock supra trans) those 5 speeds will handle about 700hp and high 600ftlbs of torque believe he ended up with about High 500 whp on moderate boost levels (12-15 psi)
I think motionautotv TH-cam is doing just that. this guy isn't doing anything new, he's just showing the old stuff they have done for magazines years ago.
That motor Jeff Smith wrote about had this same cam in it with extensive head porting, and less compression than a stock 4.3. It was also a pre balance shaft motor.
Hell yeah, this the 4.3L in particular, I know alot of guys that have nice s10s but cant really afford to do a swap and could use a video like this to help them out. A detailed build video on this motor would be much appreciated. There is not nearly as much content on the 4.3L as there is on the others. Thanks in advance
I have a Hyundai Veloster, I am seriously considering a 4.3l turbo in place of the 1.6l turbo. Im pretty sure it will fit with minor modifications and will be a ton better to drive.
I’d be curious to see how the cam choice would actually operate in a boat. Unlike a car, the boat could be at WOT at a lower RPM, and that slight dip in the torque curve would actually be right around where the boat would be cruising slowly or just staying on plane. I just wonder at what camshaft grind would you see water reversion? New series on boats please Richard? There’s a lot of small blocks in boats. Sure would be helpful!
Awsome vid!!!!🤟😎👍👍👍👍👍 I put one 4.3 L v6 turbo'd in my 1979 2 door Cadillac coupe deville with headers and we dyno'd it and it max hit at 516hp and 482 ft lbs tq @ 12.9 lbs of boost..Beyond what the original 425 BB it came with(180hp 300 ft lbs tq...
Do a 3800 series two and three!!!! The l32 and l67 in particular I’ve heard are incredibly stout little engines. As in 700+ hp reliably on stock internals
I LOVE the 4.3l v6! I'm really impressed with what you did with the supercharger. On the subject of other overlooked motors, I have a copy of a junkyard gems article from Hotrod mag a few years back, where they put mustang 4v heads on a 4.6 modular v8 and tried a few different intake and carb options, and made like 700hp on I believe a stock bottom end. The ability to make respectable power like this from overlooked motors really makes this a fun hobby.
The “Other guys” (me) would love to see more 4.3L V6 dyno sessions!
most definetly. these are stout engines.
Absolutely 😀
I've been doing a low budget turbo build in my s10. I like seeing this.
I have a running 4.3 in storage I want to make power and swap it into my stock s10
Yes more 4.3 stuff..gt45 turbo next?
Ran into this video again, and still impressed. 😂. Stock powdered metal rods, stock cast pistons- most likely with factory ring gaps, stock heads, and stock exhaust manifolds. Throw a moderate cam into the mix, a generic centrifugal compressor, and no intercooling, and it lays down comparable power to the Ford Raptor’s Ecoboost... with only one camshaft, pushrods, and a carburetor too. 🧂🧂🧂
The 4.3 is certainly one of those engines that you can hammer the shit out of for years and years and it will keep on working.
Very true. Going on 12 years.. I’ve raced everybody willing to run off red lights. Hammered through swamps in 4 low. Gooning down dirt roads like I’m Ken block. And even jumped it like the duke boys. The 4.3 is an absolute STUD. Little gutless. Just enough oomph to have fun..but a STUD. General maintenance and a couple fuel pumps is all it’s asked for. Creeping up on 300k miles and it’s just happy as can be.

We hauled wood with it, but when I got my hands-on it. I was literally just hammer on it and hammer on it and hammer on it. Laid rubber everywhere. Yes, we did lose a transmission, but Hey, it was still going at over 500000 km before he sold it. That engine is a representation of what GM could do.
I love seeing stuff like this being built. I'm SO BORED with seeing an LS or coyote being built
Thanks for giving the little 4.3 the love it deserves. LS swaps are starting to get old. Can't wait to see the other engines you'll be running.
The new 4.3 looks to be a "LS" That would be cool to see
A Totally Awesome Build
I love the 4.3L engine, it's a little workhorse! I have a '95 Chevy 1500 single cab w/ a 4.3L. I use it all the time towing vehicles with a metal car hauler between Texas and Missouri. Does great going up them steep hills with the a/c and cruise control on. Vehicle never strains and never slows down with cruise control on. I have two fairly low mileage stock turbos off of two different Subarus(Sti) that I been waiting to use on the 4.3L. Guess it's the perfect time to do it, since time is all I got now lol. Thanks for all your hard work on all these videos! 👍🏼👍🏼
When you say steep hill, and Texas and Missouri, it's very contradictory.
@ihategooglespooks
Yes I've been to Texas, and Oklahoma. 3% grade for 1.5 miles isn't much. Even a 5% for 1 mile. You've obviously never been west, 5-7% grades for 15-20 miles.
Good stuff mate.
@@johncholmes643 How is my statement contradictory? The highways are not flat all the way there and back. Just cause something isn't as much or the most isn't contradictory. I wasn't even comparing grades of different highways. I have driven my fair share in Nevada and California. Seen the runaway truck ramps. My statement was a testament to the 4.3L engine, if even for 1.5 miles(actually further), which is more than enough distance and time to get results. I find it interesting in your other statement that you been to Texas and Oklahoma, but didn't mention Missouri. Sounds contradictory.
@@Second-gear
Back when I was Tractor Pulling for money, I showed up in Kentucky. An old boy pulled in with a 6.9 Ford F250 pulling a 42' enclosed trailer. Just not used to the flat lands of of that country.... it certainly is different.
US of A, the only country in the world where a 4.3 liter engine is considered "small". 😄
Umm Canada as well dude
compared to a typical V6 motor from say, BMW, its actually physically smaller and lighter.
Lol, so true in South, Central America and Caribbean a small motor is less than 3.0 anything above is considered big
Australia would beg to differ. dudes out there running blown or turbo 10L motors just to do burnouts lmao
No replacement for displacement 🇺🇸🇺🇸
I’ve always wondered what a 4.3 would do with boost, pretty damn impressive. 👍🏻
Same here. Since the 4.3 is based on the SBC, you can use a bunch of SBC parts (rods, pistons, valvetrain components, timing sets, water pumps, etc). But there isn't much available for heads and intake.
Picture putting a torque storm supercharger on any 4.3 engine, Instant gapplebees!🤣
@ fat middle aged white guy thanks for the heads up. Like the name, don't know how you got it since that's most of us lol.
@@JSmith-wu9no you're correct about the sbc rods. Eagle does make a H-beam rod for the 4.3L however.
Werent 4.3 turboed in the late 80s? Thought grand nationals had them
Had a 4.3 in my Zr2. I sold the truck with 252,000 miles on it, tons of off roading and not one problem with the 4.3 in it.
DAMN good Engine!!
I’d love to see more v6’s built im surprised that the aftermarket didn’t try to do more with them considering the cyclone

@@BlackFyreGroup its the one used in the Cadillac camaro and i think the colorado and canyon minitrucks. They have made a ton of them and they are kinda popular for miata swaps as well.
There was a brodix 23° v6 head for a while but it wasnt really a street part and was really expensive. A couple guys use to push them really hard in race classes that had lb/ci limits and do pretty good. The things that make them good also killed the aftermarket, a v8 almost always fits.

Was going to do an LS swap on my ‘91 Sonoma, but decided to do the 4.3 with boost.
That in a nice S10 or Blazer would be cool AF and fun. I like LS Swapped stuff but love odd motors.
That was exactly, what I was thinking! Put that torque storm supercharger on any 4.3 engine s10 or Jimmy vehicle and instant gapplebees!
Ls swaps are boring. Check out my nitrous 4.3 on my page
Or put it into an Astro, turn it into a sleeper that can carry 7 of your friends.
@@chazzcoolidge2654 that's alot of weight to be lugging around though. Check out my 4.3 powered hotrod, only weighs 2340 with me in it lol
Can you still run fuel in
What i like a about the engine is the engine pulls all that weight and trailer and for 30 years. Mine is 1996
I’m down with seeing any engine content. Idc if it’s a 700 ci big block or flat head Briggs and Stratton. Keep it coming!!!

I had a 93 Typhoon in the early 2000's and i was blowing doors off of t/a's, mustangs and camrro ss. It was a stop light warrior w 350hp and 415 lbs torque.
Sounds like you had some work done to it. I had a Syclone. Fun toy.
The 4.3 made the Syclones and Typhoons beasts.
Gm brought a couple of Typhoons and Syclones to Detroit Drag-way in late summer of 1990, before they went on sale, they were ripping off low 12's like they were nothing at a bumpy, slippery track. I remember the Gm employees driving them saying, these were TWEAKED a bit, but production versions should hit easy high 13, with very little TWEAKING! I also remember them saying GN drivers wont F with these when they hit the street.
I have a 88 s-10 Blazer, (20 years) but I still want one of those.
@@mikef-gi2dg meanwhile the gn drivers were already modding their 3.8s to whoop that awd ass LOL.
It made them decent. They were good in cold weather and only if you got a good launch under boost. It took 13-14psi of boost to make 280ish hp. That really isn't impressive. It was only impressive for that time.
The turbo made them beasts.
@@frigglebiscuit7484 look on YT for the father-sin that built a S10blazer turbo AWD FLYING MILE speed was Unreal!!! OEM tx case.
AWD can be a Huge advantage.
GN 3.8 responded VERY WELL to simple mods & EEPROM CAL!!!
GNX is a rare bird, and only a Krazeee person would mess one up! I worked with McLaren engr doing the GNX motor. Hand ported 3.0 head, ceramic turbo, and who knows what else they did internally!
GNX is an incredibly rare collectible.
I owned a 4.0L 1992 Ranger, I raced 4.3L alot. It was a fight with that 4.3L. it's a strong engine
Just start making a series called "The Other Guys" so theres organization for us viewers :)
I would be interesting watching him try to figure out how the Honda guys make power.
is this directed at me?
Why? Do you only want to watch LS videos or something?
I'm a mopar guy. So *all* these videos are the "other guys" motors.
Richard Holdener if your question was to me, yes. Though your channel is geared towards v8s (as it should be), I would enjoy seeing a knowledgeable engine builder throw some internals and a big turbo at a b series or k series Honda engine.
@@youtubeisbroken241 Richard has stated in previous videos that he has plenty of experience with Honda 4 cylinders. Keep in mind he's been at this for a long time so he's been through many "trends". I suspect a future Ford Godzilla trend. I love LS engines and anything that's well designed and makes power for that matter but that new Ford big block looks like it's gonna be a game changer.
richard.this series is a gold mine of info for us older gearheads from the past,who allways wondered "what if..."many of us have no interest about what has been coming out of detroit over the last 2 to 3 decades.thanks for representing us common working men who also wonder "what if...?"
I actually tuned one on a chassis dyno back in 2014. It was in an O3 S10 with a 5-speed and factory port injection. Mods were: cam, long tubes and a centrifugal supercharger on 10 PSI. It made 350 hp at the wheels on a mustang dyno. Factoring in a 15% driveline loss that puts crank power at about 410. Since you run yours without accessories, made 3 more psi, ETC, that roughly puts them on the same plane.
i like all the math
@@richardholdener1727 shootin from the hip ballparking. lol
Sounds like the kit on my truck, hangs around 10-11psi once it's fully rolling. With the 4l60 it's best time is a 12.9 so I'd guess in the range power wise of where you're dynoing.
@@richardholdener1727
Im curious to know how it would run with the stock fuel injection. Mine is a 2004 xtreme blazer
Just ran across this guy's channel because of the 4.3 turbocharged and figured I'd throw in my two cents I've had a few of the s10s and blazers just lost my one owner ZR2 that was special ordered as a five-speed in a fire.... 😞 I love that Blazer probably never find another one like it that's that clean anyway the clutch went out on me so I did some research while I had it apart and decided to do some testing the stock 4.3 flywheels for the five speed are ridiculous heavy best I can remember it's 44 lb and just so happens the flywheel for a five-speed 350 vortec only weighs like 11 lb other than that they're almost identical so I decided to try it and was amazed at how much better it ran how much more responsive it was with the throttle and how much better it drove and shifted couldn't find a lot of info on it so figured I'd put it out here on this in case anyone else has ever thought about it I'll do it to every single one I have from here on out LOL
In the early 90's when i lived in P.R we use to install 4.3 on old corollas and samurai jeep with NOS and hurt a lot of people feelings...
look up grandma vega. FB and YT
This would be completely crazy in a little Vega sleeper, stock wheels with Turbo 350, 8.8 rear end with 3.73 and disc brakes from an Explorer. Complete super SLEEPER!!
I've been wanting to see an "Other Guys" kinda show for a long time. I'm tired of every show being about an LS, or a SBC, or a Chevy, Ford, or Dodge crate motor. I'd love to see the creativity of older engines with modern technology thrown at them. Thank you!
The tech is here, we all just have to learn from each other and Rich is blazing that trail!
Thank you! My favorite vid so far. I’ve moded my 98’ Blazer’s 4.3 with a comp cams 266HR cam, ground off the teeth of the balance shaft, trick flow chromoly push rods, comp cams pro magnum roller rockers 1.52, minor head port/gasket match, HP Tuner Suite. Surprised how much power you got. You Sir have my subscription!
My all time favorite build as of so far
Love the 4.3 Vortec V6 engine. They are fantastic engines.
Man Richard!!!!! Love this vid. I can't wait to build the 4.3. Your assessment of "real life apps" is great meaning , boat cruising around the harbor.
400M was one of my favorite engines. They were a dime a dozen, always 2bbl, seldom ever abused because they didn't make any power.. basically they were a tall deck/long rod Cleveland. Thanks for the vids man!
stroker Cleveland in the house
Jon Kasse used them to beat everyone into submission in the engine masters challenge. Granted he is a wizard, there is something oddly romatic about an engine out of a lincoln taking top prize.
ill take a 351m, please.
I snagged a 351 Cleveland for 800 bucks with an entire f150 attached to it lol. Even though it was old and worn out it still hauled ass but it needs a rebuild so idk if I wanna keep it and rebuild it or just part the truck out.
Love this channel, no nonsense approach and not just LS all the time like most other automotive channels.
i look forward to seeing testing on the more uncommonly built engines, I think they are more interesting. A Ford 300 straight 6 would be a cool one to build, there are a ton of them and there is decent aftermarket support.
If Richard wants to do a Big Bang with a 300 Six, I would love to see it. I would really like to know how much it can take.
Holly efi twinturbo ford300 i6 ported heads custom header larger cams.

@@corey0189 Schnieder has about the most aggressive cams for the 300 off the shelf.

It's amazing how much power this makes, roughly about 400 rear wheel horsepower isn't that bad.
Crank 459
In a dime that's all you need in a daily honestly. And itll turn heads for sure.
390 wheel but not bad put that in a s-10 and put a 4:26 diff your ripping
Really like this video, there’s not a lot of people doing much with the 4.3 V6 Vortec. Usually everyone on forums tells you it’s junk. This test proves it’s not. In fact After I’ve ls swapped my s10 I’m now going to keep hold of the v6 vortec motor and do a separate build with it. There is also a inlet manifold kit that allows you to run injectors (not spider injection system). Can wait for more videos on the 4.3 v6. Peace from 🇬🇧.
After years of getting made fun of back in high school for having a 4.3, the only engine I have nowadays are v8’s. But I still secretly love the 4.3 for how much of a workhorse that little engine was!!
A 4.3 s10 would outrun a tbi 350 1500 but not a vortec
I've seen plenty of hot rods and projects built on the 4.3L V-6. I think is is worthwhile. For many, 400 - 500 HP is fun but not out of control in their vehicles. I would think folks will use these more and more. I'd even love to see you tackle an inline 6. Great video as always.
Thats only less than half of what I'm aiming to...
I watched a load of videos on TH-cam showing what a 4.3V6 can do! An S10 Blazer running the 10's was mind blowing!
Hey Richard, great project and awesome results! I think the torque storm supercharger is far easier and cheaper upgrade, than a LS swap. God for give me, for saying that. But I really think this video opened people eyes, to the potential of this combination.
Thank you for doing it. I have been getting a lot of crap for the same idea. You validated a lot of ideas I already had thank you for doing the legwork and sharing.
Great can't wait for the ford Cleveland the 400m loves more compression and cam
I wanna see the 400 under single turbo boost. There's a lot of guys/gals out there that don't want to have to swap in a 460 and a 400 under boost would be the ticket.
I always felt these engines were mini giants.. Awesome vid. 😎
I personally would like to see you do a video and build of a 60 degree V6 such as a 2 .8 173 cid chevy v6 i think that would be cool and i think a lot of people would be really surprised at the torque and horsepower these little motors can actually make.
I have an 85 GMC 1500 that’s got the 4.3 in it with 170K and still runs.
These engines will last if you take care of them. Extremely simple an reliable.
I'm definitely one of the other guys. I ran the 4.3L V6 for my Typhoon on the dyno (minus turbo) to break it in. It made 276hp & 306lb-ft of torque thru stock n/a manifolds and Y-pipe with an untuned 850cfm carb sitting a top 3 inches of carb spacers (to get the carb linkage over the fuel rails) while running 91 octane from the mom & pop gas station from down the street. It was built to handle 30psi AND a 100 shot of nitrous. Currently I'm running the stock turbo & boost (14.7psi) as I'm sure the stock 700R4 won't handle the 1st AWD boost launch I do but I can't wait to stick a bigger turbo on & turn up the boost once I finish the 4L80E swap.
The 4L E 80 is a butter trans than the 700 R4? If so that is good to know I have a 4LEDA and my S 10 and was thinking about swapping it out for a 700 are for if I get a 350 or 383 stroker crate motor thanks for giving me the heads up very appreciated
I have an 85 cutty and was thinking about a 99 4.3l vortec for a swap. Thanks for the light, bruh. Your show is major informative and saves time and money.
Suggestion for The Other Guy candidates: Late model Chrysler LA engines, specifically the Magnum 5.2L and 5.9L.
In my area those a dirt cheap because people are convinced that they're terrible engines that can't make any power, I think those people are wrong.
Ok big chevy and mopar guy here that 5.2 on 12psi is a total animal. All did to it was a mild cam swap and then a tt setup and my 79 dodge is making 680hp to the wheels. I probably should have gapped the rings but the motor had 170k on it and i didnt want to bother with it.
The magnum 5.9 is easily the best bang for your buck as a direct swap for any mopar that came before it. I import them to Australia coz it's still better value than reconditioning a 40yr old LA360.
The disrespect they get is huge. I've had people literally tell me it's not even possible to make 400hp from a 5.9.
Also they make pushrod oiled shaft mounted rocker arms to allow a retrofit of LA style cylinder heads onto a magnum short motor now, so the "bad flowing magnum heads" is no longer such a big deal breaker for high hp builds.
Stacey david did a super charger on one back n the day and it was a regular cab short bed like a 99 or 2000 and a 5 speed
And I agree I knew a guy that had a cam only Dakota rt back n the day and it was decent he did heads and Intake then the truck was totaled and he kept the engine and maid it a stroker and swapped it into a regular cab short bed Dakota with the insurance money lol
Edelbrock heads, Edelbrock air gap and a good cam and you can easily exceed 400hp with a 5.9.
Thank you so much
I’m the other Guy, we’re heading in the right direction but love to see 4.7 L dodge upgrades supercharged turbo hedge cams everything
4.7l dodges blow up easy enough stock I don't think they'll do very well with a cam and 10lbs of boost.
They only blow up when people do not maintain them. I had Crane 218/224s, 08 manifold, and headers on my 03 Dakota. Used to spin it to 7,000 rpm almost daily. Mobil One 0w40 and Mobil One filter every 5K. Truck is still going strong. My brother still has it.
@@konnerkramer329 i have a 4.7l in my jeep GC fully ported heads no cats ,exhaust, and custom built CAI, and it get down pretty good and has over 340k miles on it and doesnt burn a drop of oil or tick when cold or winter when first started, worst part about them is if they get a lil hot they drop valve seats, they come with factory forged rods and pistons atleast the 02's did in the jeeps, i hung with some turbo honda's with 4 people in my jeep and its all wheel drive so that doesnt help it but wonderful in the florida rain :),
i think i took about a solo cup's and half worth of alum out of each head when i ported them and did all the bowl blending, lil chamber softening did all the porting @ 219k miles.
They have a really long intake runner in the head and its very restrictive and the exhaust side is very short and not so bad but needs work.
I really wanted to turbo it but when i was looking into it i could not find anyone that could tune it, so i didnt get to much further ,maybe now there is someone. i could of did standalone but i wanted it all stock ecm so everything would function normally , also the 4.7 H.O. has about 10.2 comp ratio and the non H.O. has 9.5 but the H.O. has about 16 more degrees of duration and about .020 more lift than non H.O.
I still have all my research on doing the twin turbo's for the 4.7l but the jeep GC platform has like no room for that kinda stuff, the pick -up would be better suited for room for twins of a decent single.
@@chrisdeez2176 I'm sure you can make them pretty peppy but do that work to a 318 or a 360 any you'll run rings around a 4.7 all day. Ive never personally messed with the high outputs so I couldn't tell you but I do know the non HOs don't have forged rods and pistons. They're not terrible engines but I don't know why anyone would ever want to build one. I built a $800 355 for my k10 that makes more power than a "High Output" 4.7 does. I know there's an entire liter of displacement difference but my block is a 1968 casting with 1972 993 heads and an RV cam with some .030 over flat tops that came out of a 350 irrigation motor that ran on natural gas... stock crank, rods intake, and carb. And it makes the same top end power and more low end torque than the ho 4.7s with port fuel injection, electric ignition and 2 full points of compression more.
Love what your doing saving us little guys alot of test money so more can go into our builds.
That was impressive! I am very surprised how good the NA numbers were without headers. This is a viable engine. Thanks for opening my eyes to this.
Richard, thanks for all your comparisons and information. You have a knack for posting useful comparisons and shedding light on less documented engines. I found your channel a couple days ago and we must think alike! You have provided facts and data on many combos and parts I have wondered about. Thank you for sharing your hard work, it is greatly appreciated!
Glad it was helpful!
This guy is a engine building genius. I love the idea of running a v6, just to be different if nothing else.
What a blast it would be to have him on a project right?
Thank you so much!!! I LOVE IT!!!! 500 hp divided by 262 cubic inches equals 1,71. I agree with you. I would love to see more love for the 4.3. An option I am considering as well. Speedway Motors offers ceramic coated shorty headers for the 4.3 as well. A great set of CNC heads would make this a miracle motor!!!! Add a TPI intake and you are gold !!!!
Love videos with the oddball engines. I think there are so many good engines out there that are largely ignored
Thanks for the video, same thing goes for the 3.8/4.2 ford ive been out of the game for a while but guys were really pushing boundaries in 2003-2008 with 6-700hp 9 sec et's
I'm loving this channel. All the engine's he talking about as the "other guys" is the stuff I love to see. Tired of seeing the same engines. 👍👍
Been dying to see a 4.3 with boost. Making dreams come true one video at a time. 👍🏻
Glad to see someone finally do some 4.3 love. There are a zillion of these just rotting away in junkyards. Tough as hell little engine and it's obvious there is power hidden in there.
They are strong ass little motors a lot of people don’t realize it is a 350 minus the back two cylinders just wish there was a decent selection of aftermarket performance parts for the 4.3 L but unfortunately there’s very little to none
GREAT VIDEO RICHARD!!!! ONE OF MY FAVORITES!!!!
As long as you're looking into alternatives, comparing this 4.3 to GM's 60° high value V6s and Buick's 90° V6. Both have aftermarket support and the 60° V6, despite being the smallest both dimensionally and displacement wise, can make astonishing power with a cam and spring change.
The 3.9 v6 that came in Uplander van, Impala etc. from 2008-2012 will make 500 hp with a GT35 turbo and E85. There is an IROC somewhere on youtube running 10.56 with that setup
@@VTLIFE-so4dc that car ran at my local track. It did well in a race series I followed but I haven't seen it out since a few years ago when police were harassing people going to the track.
I built a 4.3 like this about a decade ago, same intake, same cam. Added long tube headers and did mild porting. It made 435 ft lbs and 389 hp. Motor came out of an 02 s10 extreme with 20k on it.
Damn that’s stout. Wheel or crank?
I would like to see what could be done with the Ford 3.7. These engines were placed in Lincolns, Mustangs, and F-150s. These engines can be had cheap, the internals are relatively strong, have some aftermarket support, and can produce good power even at low boost. I have one that 420 rear wheel horsepower on a Mustang dyno at only 9 lbs of boost. I'd like to find out the limits of that engine.
I'll tell you what you can do if you own one in a FWD car or truck: Be on top of your timing chain driven water pump.
If it goes out it will take your engine with it. The tell tale(weep) hole leaks coolant INSIDE your precious high tech, high dollar engine.
The ones installed in the F-150 apparently have different design.

I love my 96 Chevy c1500 4.3 v6. Just finished rebuilding the engine. Bored 30 over with high compression pistons. Compression is 9to7.1 with thinner head gaskets and running with a computer friendly hydraulic roller lunati 268 276 cam with 503 lift 111 lobe separation. With a Tuned computer. My pickup put down 244 horsepower to the rear wheels and 267 ft of torque. For being all motor. I'm very happy.
I remember when the first of the v6s came out n was impressed back then of the power. Some need to remember that coming out of the years of the gas shortages and smog years late 70s and 80s horsepower was low. Early 80s corvette smallblocks had 180 or so horsepower!
I have a 2002 S-10 that I bought it brand new, and its been my daily driver every since. In June, it will be 19 years that its been my only vehicle. Ive been wanting to do a performance build on it for years, but like you mentioned, there are basically no performance parts available for these engines. Other than camshafts, and headers. I wish so badly that they had performance heads available for them. Because if I build mine, I would want to keep it N/A. Would love to see many more episodes centered around 4.3 performance builds. We S10 guys especially would appreciate it more than you know. Thanks for all this info Brother!
I'd be curious to see the blower results with the stock cam. It was interesting to see the torque curve for the blower run was similar to the aftermarket cam, just moved up the rev range a little.
Many years ago I put a modified 4.3 v6 and 5sp from a camaro and modified 8.5 rear end in a 81 chevett. It was quick and fun.
Those are good numbers for that engine, especially with iron exhaust manifolds.
I love the 4.3 amazing what you got outta it. Definitely a sleeper 🤠👍
Stoked to see you doing this engine. I just pulled one out of my ‘02 Silverado that you can have, it’s kind of a turd without boost, and like you said little to no aftermarket support. It has a five speed and leaks from every gasket but I’d donate it to see you boost it to the moon!
I'm lookin for a 4.3/5speed to put in my '56 Studebaker Power Hawk. Wanna sell yours? Thom
@@thomboz1 I’d give it to you to get it out of my back yard. But can’t make any promises on its condition. Had about 200k when pulled
I had a 2000 S10 extended cab with the step side bed and the xtreme appearance package. It was a 4.3 auto, I put 4.10 gears in the rear with a locker, the transmission had a corvette servo and a shift kit, and for the engine, electric fans, under drive pulleys and a healthy 150 wet shot of nitrous. That truck was fun to surprise people with. It did have a little suspension work but nothing really special.
What about the Buick 3800. The m90 supercharged motors particularly are still being modified.
I concur
Nte 35050 I’ve got one. Weakest thing there is the trans
The M90 blower is in an of itself kind of a choke point. I'm sure those engines could pump out some impressive numbers if you swapped the M90 for a bigger blower, or a turbo.
yep
Go adapter plate honda trans???
My 4.3 was to date the best vehicle engine I have ever owned. Great motor, was always reliable for me, had good power too.
Thanks for the videos! I always thought the "other guys" were Buick, Olds and Pontiac LOL!
You and me both!
Your continuing the work and love of the odd stuff that I read about 30 years ago in "V-6 Performance" by Pat Ganahl. It was actually written in the early 80's when the 4.3L was just coming about, but guys like Grumpy Jenkins were already pushing 450HP from the small block V-6 just to see what it could take. I still pull that book out and look it over from time to time. I originally bought it to research a 60* V-6 engine build I was doing in high school, but was disappointed that the book was written before the advent of the TBI injection I had decided to run.....still a great read and a blast from the past!
I want to see one of those newer LV3 EcoTec3 4300 all boosted, all LS derived, damn thing looks like an LS1.
They have balance shafts no good
It's basically the new LT V8 with 2 cyl looped off. Only found 2 that have been turbocharged on the internet.
@@ohhthepatpat 🤨That's vague at best to claim such a thing. Care to elaborate more ? 🤔
@@GIGABACHI balance shaft motors are not good to build for performance period they don't withstand rpm and they don't make a balance shaft delete for these motors
@@GIGABACHI best to get a block pre balance shaft get later model heads then go from their waste of time money and space in my opinion just go to a Nissan vq35 they are easily 300hp only downfall is you can't just slap a intake manifold on and carb and go
Yeah. I want to see more videos on the chevy 4.3l v6 engine. Please and thank you sir.
I know they are still a bit hard to get in the wreckers but I would love to see a new ecotec3 lv3 v6. They make a ton of power, camshafts are just making it into the pipeline and all the lt1 corvette goodies can make them rock. How you run them they would probably make more than 300hp stock.
Timothy Bayliss is that the v6 that came in the camaro with camshaft and oiling issues
@@utahcountypicazospage5412 no, it's the 4.3l v6 that came in full size pickups 2014- it's based on the gen5 push rod architecture. Aluminum block and heads. They make 285hp SAE, like 40hp more than this engine before the blower.
That's great I've been wanting to build the one in my 96 blazer for ever now.. now I know where to start thanks very very much! But I'd love boost so I'd like to see 20psi at peak and probably have cut off at 23-25 psi but I'll get there one day!
I would love to see what you could do with a Taurus SHO engine. The prettiest engine in the ugliest car............lol
Built by Yamaha......lol
I want to see how they respond to boost. Or cams. Or anything really
The blue turd has made big power with his SHO, it's on methanol to
He just made it into the 8s 1/4m
Threw a built stock H pattern transmission
Volvo makes a few models with v8 Yamaha engines. All of them would be amazing with boost
@@ufarkingicehole Noble M600 has a boosted Volvo V8
Probably very hard to find performance parts for that engine. Would need custom cams cut. One off engine management.
It would be cool, but impractical.
Wow that is just mind blowing. I mentioned doing this on another video. He answered me. Lol. Idk. ? Don’t underestimate those v8-2=v6 engines. Great videos
Oh yeah I really wanna see build up of Ford’s 289 and 351 cleveland and sure the 400m too!!
As the 400 is basically a tall deck stroker 2v cleveland. 😁
And maybe add the 429/460 to the list too. 😎
Especially I wanna see the Boosted applications!
As those engines are pretty common at my ”enviroment” 😀👍🏻 Would be awesome
Love it forgot to mention the 4.3's are bullet proof, great video
I love the 4.3L v6. The balance shaft version needs a small modification to ensure the balance shaft doesn't shake and throw spark knock codes.
What's the modifications?
@@claytonhaske don't remember but there is a service bulletin they put out for it.
Thanks for giving the 4.3 some love! Would love to see more with the v6!
Heaps of Cleveland stuff in Australia. They were the go to performance engine for a long time
Thank you for getting out of the box. I had one in my Astro van 4.3 vortex and that engine ran pretty good. I would like to put one in my Jeep for a future build.
Now this is the test I’m talking about!!!
One of The Best Engines General Motors Ever Came Out With Same Engine I’ve Got in My 97 Chevy 1500 4.3 With The Balance Shaft 😀😀😀😊👍🏼
jesus, 13.3 psi on a mild build.... Those IAT's...
Glad to see the v6's are getting some love. Would be really interesting to see a shoot out between the 3.7 cyclone v6 and chevy's 3.6
Hey Richard, I guess I’m one of the other guys. I have a 292 y block Ford that is going into a 1931 Model A. I’d love to see you do one of these y blocks and see how it goes.
Love that everything is dynoed and as they say the proof is in the pudding!!!
You’re really inspiration man! I wanna see a magnum motor on the dyno! 360 magnum with and without a turbo :D
Very cool Sir! I always wanted to supercharge a 4.3 S10 but ended up with a V8 every time
How about adding a cam+turbo to a Vortec LL8 and big bang it, see how close it can get to a 2JZ. Jeff Smith wrote about one back in 2011, pushed 470 on 8lbs, curious to see how much was left on the table.
trdscfjc the issue with that though is there aren’t any aftermarket cams, or really anything aftermarket for that matter available for the atlas series engines. That’s why so few people mess with them
I remember someone on SupraForums swaping one into a MKIII supra Using an AR5 Transmission which is basically A toyota R Series Transmission with a GM bellhousing (R154 Is stock supra trans) those 5 speeds will handle about 700hp and high 600ftlbs of torque believe he ended up with about High 500 whp on moderate boost levels (12-15 psi)
I think motionautotv TH-cam is doing just that. this guy isn't doing anything new, he's just showing the old stuff they have done for magazines years ago.
That motor Jeff Smith wrote about had this same cam in it with extensive head porting, and less compression than a stock 4.3. It was also a pre balance shaft motor.
Hell yeah, this the 4.3L in particular, I know alot of guys that have nice s10s but cant really afford to do a swap and could use a video like this to help them out. A detailed build video on this motor would be much appreciated. There is not nearly as much content on the 4.3L as there is on the others. Thanks in advance
I have a turbo 4.3L coming up
I have a Hyundai Veloster, I am seriously considering a 4.3l turbo in place of the 1.6l turbo. Im pretty sure it will fit with minor modifications and will be a ton better to drive.
No way 😂, I'd rather just build to increase boost . Way cheaper and the 4.3 is bigger, isn't transverse, and fwd to rwd is hard/pricey
My dad loved his '63 Falcon with a 260. "Never lost a race". I loved my s-10 with 4.3 auto never let me down.
I’d be curious to see how the cam choice would actually operate in a boat. Unlike a car, the boat could be at WOT at a lower RPM, and that slight dip in the torque curve would actually be right around where the boat would be cruising slowly or just staying on plane. I just wonder at what camshaft grind would you see water reversion? New series on boats please Richard? There’s a lot of small blocks in boats. Sure would be helpful!
Awsome vid!!!!🤟😎👍👍👍👍👍 I put one 4.3 L v6 turbo'd in my 1979 2 door Cadillac coupe deville with headers and we dyno'd it and it max hit at 516hp and 482 ft lbs tq @ 12.9 lbs of boost..Beyond what the original 425 BB it came with(180hp 300 ft lbs tq...
519 HP AT 13 PSI?
Do a 3800 series two and three!!!! The l32 and l67 in particular I’ve heard are incredibly stout little engines. As in 700+ hp reliably on stock internals
I LOVE the 4.3l v6! I'm really impressed with what you did with the supercharger. On the subject of other overlooked motors, I have a copy of a junkyard gems article from Hotrod mag a few years back, where they put mustang 4v heads on a 4.6 modular v8 and tried a few different intake and carb options, and made like 700hp on I believe a stock bottom end. The ability to make respectable power like this from overlooked motors really makes this a fun hobby.
