For all those in the comment section whining about the self imposed limiting, this engine is a mild daily driver. The owner will be thrilled with anything around 250 HP and 400 Ft Lbs of torque. And so would I. It's not going to the drags.
warren hymes it did 219 naturally aspirated, with the turbo should be close to 300hp if not over...
They got the torque they came for. That’s good enough. The components that are still oem in the block won’t be able to handle much more. It’s a cool old school Chevy, not a 2JZ.
I would love to see the potential HP/torque with a better lower end/rods/pistons and head/valve work. Full boost would be cool to see after all modifications, hammer it till it self destructs just to see the rating. ;o) By the way, I love seeing a strait 6 hopped up,,,,,,,v8's are boring after seeing this, thank's!
mark jeffries agreed.
I love torque monster low revving engines. My daily has 150hp and 270ft lbs.
But if I had $5+k into a little I-6 with a turbo, id expect to make alittle more then a healthy v-8...
In Brazil, with heavy preparation + turbo this motor make over 2.500 hps and 170 kgmf of torque. Search em YT for "Opala Celso Camargo" videos.
im a ford guy and like the 300 six more but its not a “real torque monster” compared to the 292... its literally the same output lol 160-170 hp and 280 ft lbs N/A for both engines and no real suprise since they are essentially the same displacement......
like the bit where he says it sounds like a skyline motor
I'm glad you did a chevy inline everybody else does the other companies inline . inline 6s are great they make awesome torque and are great on gas. impressive numbers on stock parts.
I'm just so glad to watch a c10 getting something, anything other than a freaking LS Swap. 🤢. I'm so sick to death hearing that term parroted over and over and over like it's the best unique thing.
this is is the third or fourth time I've watched this,, and my little hairs stand up just like they did the first time from seeing that torque curve!!!!!! i need !!!!!!
Here in Argentina this motors are used in category "TC" límited to 183 cubic inch and 8500 RPM. Are naturally aspired and gives 380 hp.
Argentinian enginners do magics
Those are the exact same power numbers for a stock 472 cubic inch Cadillac. On a 6 banger. That's VERY impressive.
Yeah man, I love those old 292 - 6 bangers, had a few of them myself! And that’s a awesome one y’all built there!
I think it's awesome you guys are doing this with inline 6s. Just love it.
Work of art come together. Wonderful work all involved! (Not sticking a clean rag into the exhaust port while scraping the old gasket off did make me a little woozy though.)
Right into the turbo charger that loves FOD (foreign object damage).
I've two 300 i6 fords and a 5 cylinder Volkswagen. The i6 and i5 were very torque happy.
Yea pops got mom's old 07 Jetta with the 5 , he said he's impressed with the low end.
He came from a golf TDI before that so it's saying something ..haha they sound nice with a good exhaust too 😄
And I love that 300.
I see alot of em often at work , mobile generator service.
Worst problem I get is a leaky water pump from lack of cooling system maintenance,not it's fault.
@@MrTheHillfolk very torquey indeed. Very easy to pass at highway speeds without downshifting. I had a manual. It was fun
@@MrTheHillfolk I live in Florida. They run the roads a lot down here
@@thejuiceisloose8703
Yea you guys have alot of nice iron ....I fixed a rust car here in the northeast , never again.
Will travel for no rust 😄
I would like to see y'all guys convert a in Line 6 into a diesel. That is the closest gasoline motor you can get to being a diesel. The fuel gets pretty heated but exhaust manifold like a diesel. And it has timing gears like a diesel
I have been wanting to do a turbo GM straight 6. Those numbers are perfect for a daily/fun truck that only weighs 3k lbs. If I did this I would probably try to build custom manifolds though. You are losing a bit of efficiency by going with that wrap around exhaust system over a turbo header. Building a more modern intake manifold with equal length runners, plenum and throttle body might also help as well.
Ford Australia did push their Barra 6. See Summer Nats, 1800hp? Maybe more now
Howdy something awesome to watch TH-cam ."Aussie ford Barra xr6 turbo in speedboat."sight name Sam tweetie 13 min long shows Australian engineered straight 6 cylinder going up Aussie outback country river travelling heaps of KMs miles in no time.great scenery and driving skills.goes like a rocket it sings mad motors.enjoy watching you'll love it trust me.see an Aussie engine sing.
The 292 is the best L6 ever built period
eh, that's debatable, im a gm fanatic but the 300 i6 ford was a bulletproof engine
I wish they would have revved it higher and ran an electronic boost controller. They could have carried that cylinder pressure and torque out higher to a make a ton more power. This is encouraging though! I'm building a AMC 4.0l with the same turbo, I'm aiming for a similar NA power, but more horsepower, similar torque.
Needs forged internals before any more boost.
GM offered these in its "squarebody" crew cab and crew cab dually trucks up until '91. This turbo 292 setup needs to go in one of these. Then drive it to Colorado and do an Ike Gauntlet pulling a weighted horse trailer with the TFL guys. Easier said than done, but what a series that would be.
Pat "If that was a v8, it be making blaw"
Engineers around the world "Pat you should know better than to say something that woefully inaccurate."
What??? Amish Mike not wanting to break 400hp, this years breeding season must have left him very fatigued!!!
Still waiting for you guys at Powerblock to build and run a vehicle at the Silver State Classic Challenge in Nevada.
Great video! I was always impressed with the rare 302 GMC I-6 truck engine.
13:13 his face says everything lol
I'd like to see a shoot out between the 292 Chevy 300 ford and 225 chrysler and the 301 GMC
Goaty man has even pens. Ready to write...always.
Don't get me wrong, loved the build. Ozzies do some amazing things with 265 inch 6 cylinders as well. worth a look.
In stock dress, these engines could brake anything that was bolted behind them. Nice project.
That initial build was most impressive but I was a bit surprised that it didn't get closer to the horse power per cubic inch range.
Wow ,500torque👍 Only thing should have flat top Pistons. 🚩
I thought that thing was going to shoot off the screen.
Grab yourselves a Barra engine from OZ and boost that puppy
POOOOOWERRRRRR
Had a 69 Chevy stepside long bed pred pickup truck in the early 70s wasn’t fast but boy could it pull. Moved so had to sell☹️
Incredible power to weight ratio.
I’m shocked at how good that engine sounds
There is a reason all the good diesel truck engines are in line 6 cyl design
nothing magic, just convenience
Besides cost nothing really
I’d love to build my 292 similar to this. I have it in my 1949 Chevy 6400 welders service truck.
Those torque numbers from that engine! 🤯
I honestly doubt it was even close to "blowing." That thing would probably take double the boost before it even batted an eye. But I guess if it isn't necessary
Jezzzz pat. You got enough pens?
Yeeeeees. Got a 66 c60 3ton with the 6. This was the combo I wanted to do....and they did it for me! Super awesome 6! Cant wait. Itll still be slowest and slower with my gears lol.
I've been waiting anxiously since the initial build and very happy with the show. You guys rock.
May I ask you for a little more information? Price as built and shown and cost per horse power
DontBe StupidAnymore I’ll get some push back for this answer but it’s not near as cost effective as an LS swap.
That being said this is not built for cost effectiveness, it’s built to be different than the popular or normal option. I’m guessing based on the turbo setup plus that holly system, the block work, head work and other expenses I’d put this engine in the $6500-7000 range.
I’ve got a 65 C10 with the 230 straight 6 that I am restoring currently, going all 100% factory stock.
@@adamg1180 7k would be a great price for this mill... the Turbo by itself is gonna be 3500 ish. 1500 for the Sniper. Even at 10-15k, this is a crazy cool motor with silly stupid numbers to match. I say win!
hawkdsl I agree, it has an extremely high cool factor. However it can be done with a 4 barrel carburetor setup. There are more economical options.
They should of did a shootout with the Ford 300 they boosted later on both motors surprised me
Man. V bands on the cold side are cool. Even if your only pushing 15lbs rubber boots suck.
The 292 is a good engine for a truck. If it was going in a car or possibly, dare I say it, a truck that would never be used as a truck, I would use the 250, you could get more horsepower out of a revable straight 6.
Love the build and uniqueness of it, but that intercooler is severely undersized for that application. That'd be right at home on an Omni GLH but not on the stovebolt. That's a serious bottleneck. Obviously, the truck turned out fine, but given a more appropriate intercooler it definitely would've made more power.
Very impressive build
...292 was NEVER installed in a CAR from the factory...strictly a truck engine!....
dyer2cycle
I think in South Africa they may have been found in some Holden bodied, chev badged vehicles.. but I have not seen one personally.
I have heard this from a guy who brings Holden vehicles back to Australia from South Africa . Can anyone from SA please clarify if the tall deck motor was factory fitted?
I had a 76 caprice wagon that come with 3speed on the column and 292 it was ordered like that. So there was a bubble in the hood for the valve cover. Looked funny but man that thing would pull a house down
I wonder how long it takes for the Holley to learn how to run and if it continues to make adjustments weeks, maybe months into its installment.
For folks asking about a forged crank, there was an oem one but it was actually not as good as the cast crank.
And I could be wrong but I believe Santucci’s power manual said the oem rods were good to 400hp
the first year out (1963) they had forged steel cranks, after that they went to castings--In 1966 the 250 and 292 cranks went to a 12 counterweight design that were impossible to make by the forging process (too intricate )
Build an engine that doesn't have one off custom parts but one that the average enthusist can easily re create at home , very cool project but not all that doable for most
Better yet just build the inline 6 with parts available without custom work , i had a 292 in my 74 nova built with tri power intake and headers from Clifford research , cant remember the cam but build the engine with parts available is all i am saying
Should have used a bit smaller turbo with a little more boost, would have made more torque
6:17 ... WAY too close to the turbine outlet.
@Dave Micolichek umm... Yes? Read any wideband sensor manufacturer recommendation on placement, and they definitely say to have it further away.
@Dave Micolichek I didn't say it wouldn't work.... but likely to not last as long.
lolz intercooler is indeed a bit small. but if you make a flowbucket for it you can cope ^^
also Deam for a 6 cilinder thats nice power :D
It's all alien technology!
Inflation adjusted 8000 AUD 6+ years ago is almost over 10K in today's AUD.
I dont think pat has enough pens in his front pocket
Will a engine line this with a steel crank and heavy duty rods survive as a daily driver. It's got to get better mileage than a V8. Plus it would be different than the normal hot rod.
Was it me or did that torque curve look really weird? Looked like it hit a wall and bounced off it around 3500 rpm. I see that the Y axis only went to 450, maybe it is not really how the curve really was.
I want to build one of these for my 93 k15
Pansies! 7 main bearings. That block has a shit ton of beef. Richard Holdener will show you how it's done.
If you guys used a fan in front the intercooler would get more horsepower
In beefing up the torque and horsepower how is this going to effect engine wear and longevity ? It seems rather self evident that more stress is added to the engine and thus shortening engine life. Wouldn't it be better to have a V8 to get the added power ?
The only question left is how far can you go unlimited unboosted and how far can you go unlimited boosted.
I reckon they underestimated the engines capability whats the piston copression surely the bearing sizes are able to withstand more load maybe the rods being the weak link I mean they got the gear for machining the engine sheez.
A driver? NO, you created Frankenstein with a hodgepodge of parts. A "driver" needs to be nothing but off the shelf components. NO SPECIALTY AFTERMARKET parts.
Holley is really trying to push there efi on everyone how many they give you for free damn
GMC 302 inline 6 next!
376HP and 510ft lbs-- not bad :))
250 292 300 in line six put headers change the cam put holly 500 two barrel or 4 barrel that's all you need
Valves sounded like they were loose
Can they shut the music off in the background?
While you are at it build and turbo a 478 V6
So.. how about you push them to ~2,000HP+? th-cam.com/video/miENduXJivI/w-d-xo.html EDIT - Also find a GMC Big Block V-6 to play with!
So I have a question,I have a 235 cu.in. with 3 deuces and a modern 5 sod going into a 1940 Chev.truck.My intention is to go 10 over on everything to freshen the motor,my question is what else could I do without costing a pail full of money because it’s going to be a rat rod shop truck?
Is it possible to do a 2 barrel carburetor on a 300 Ford 6 cylinder
these l6 engines in Brazil pass 2500 hp on the racetracks
What could be done with the Chevy 235-250 inline 6? Have you anything on those
Why not go with a cummins straight six if tq is your goal . You can have your cake and eat it too. With a tune stock everything else 600hp and a 1000ft lbs is very reachable, easily.
That would require more work to the truck, plus the additional weight to deal with in a c10 😁.
@@allanb3222Theyre building a turbocharged straight 6 . They are doing work. The c10 can handle 400 lbs extra just fine . Not doing something because it requires working at it isnt really an excuse.
What rockers and cam, year motor. Pistons? Great vid
just watch the previous episode where they assemble this engine, they always mention each part they're putting in.
👍
When will the project be 2uz-fe?
292 is the big block straight 6 the small block is 250cid or less I start out driving cars they were all strong running sting running Engines
Not bad for a Chebby.. unless you look at @ Mopar 225 slant six Without a Turbo.. rut roe.... smokes this Briggs&Stratton! At over 300HP!!
I am building a K30 4wd and want to build this engine what is the price you have into this engine. Right now I have a 454 FI but want the economy and power of a 6 cyl.
How about a 300 Ford?
Ford 300 NEXT!
I'd like to see a similar build with the 300 big 6 from ford. That's a real torque monster no question.
Some guys have been getting high 400 ftlbs at around 2200 rpm
I came here to say this
How about my 1970 gmc 250!
I had an 85 F-150 4x4 with the 300 and a 4-spd. I'm a chevy guy but I LOVED that little ford.
@@Shane-Singleton i miss my f150 300 6 w/5 speed.
It's 6 cyl, my heart beats faster!
These 6 cyl engines are very reliable and great for preparation, here in Brazil, the GM 250 engines in our Opala gain absurd power !! I loved the video!!! Congratulations!!!!
Six in a row makes em go !
damn you guys in Brazil and Argentina really know your thing, I've seen how the opalas move a daaaaaamn they are fast like any promod in the USA
I wish we could get the FI 250 I lines here
Good to see one of these inline 6's on the boost! You guys rock!
Pois é! Os v8 Quase não existem no Brasil! Tem que quebrar um galho com 6 cyl no Brasil. Com uma opala da certo mesmo!
Pega uma turbina de qual carro geralmente? Um s10? Diesel?
These old I6 engines are so underrated today, it's really sad.
Cause we've got dohc 24 valve engine like the 1/2J, RB, and various BMW engines.
Just means there's plenty to be had!
@@sebastienceniceros3145 Neither is capable of 2500 HP on stock block, head and rotating assemblies.
Chevy 6s, burning nitro, with turbos doing high 5 second passes in the 1/4.
Yeah but the rebuild cost of a 8v isn't much of an increase and hard to justify
I grew up with my uncle building these and blowing others off the toad. The torque is a beast on them.
Are the numbers of pens in shirt pockets are equal as Military Rank Insignia?
Pat's almost General :)
Very good comrade
It's equal to motor building badassery
Half of them aren't pens. No machinists must watch this channel.
don't forget his tool belt
Perfect program for the sunday in the moning.😎
Haha yup, just like I used to watch these on TV.
Only thing that hasn't changed is I still sit there in my skivvies and watch 🤣
Sunday cartoons for big kids
Sunday night :)
here I am
I love the torque on that engine. It would be nice to see what it would do, while towing in the mountains, with mileage data too.
My dad was the OG straight sixer and had a 51 Chevy Club Cupe, 260 stroked with 292 crank and rods, Blue Flame cam, Powerglide head, Stromberg side draft carbs, and Packard synchro-mesh transmission. This was his work vehicle as he traveled all over Nebraska as a field technician for Burroughs Corporation in the late 50s. It was a true junkyard hot rod.
ford should of kept the 300 I6 and turbo that
Look up Barra
The pickup 300 if you out a 6.5 diesel turbo in it you can easily hit 400hp stone reliably.
Perry2186 I had one in a F250 with a granny 4spd. Much better work truck than the small block V8s of that era.
@@robsorgdrager8477 True, but ford never offered them in the US. Would have scavenged sales from the mod motors...
We've got something far better than the 300 lol it's called a barra. And in ausi they don't LS swap lol the barra swap
That is such a fantastic set of numbers. Holy cow! Would be a great truck to pull a trailer with to pick up that next project car. This has been so fun to watch! Happy to see people out there not afraid to be a little different!
How did i know you would have already seen this lol
@@EfurdGarage haha... well I have an image to uphold
I’d like to see a Slant 6 Chrysler engine.
Great engine but the head has valves facing different than other engines. Bad flow in head until about 4500rpm I've been told.
Not a mopar guy, but I'd like to see it as well, hemi gets waaaaay too much attention, wouldn't make huge numbers, but interesting
They already did one.

Pontiac?
Great job guys. I love inline sixes...the torque potential from small financial input is excellent. I agree with snakeboy256...the Ford 300 was awesome. My Dad had a 1977 F100 with the carbureted 300 and three on the tree. It was a real stump puller and gave us fantastic gas mileage. The truck being a typical 70's Ford was a rust bucket and had all kinds of weird problems including cracked piston skirts but I often wondered what kind of torque monster it could be with the right massaging.
I had a '67 Nova 4-door that had a straight 6 & powerglide. Always wanted to turbo it & put a 5-speed manual in it. Flat black with red interior it was a cool little gangster car 😆
He said gangster
My buddy had a nova from the 60s. Idk what kind of engine, but it was a inline 6. We started that thing with some really old gas. That thing smoked like crazy. Heck we took it down the road put new gas in it. Ran good
What a beastly little engine!! I've always loved inline sixes. It's a shame Chevy did away with them. You can't beat the smoothness, fuel savings and torque curve. Great video guys!! 😀👌
Trailblazers & Envoys came w/4.2L inline 6. Thinking of grabbing one to throw into my daughter's 53 chevy truck we're going to start this year...but unfortunately they stopped making those too
@@kierancarter8369 I remember them. Shame they quit making them too. I never heard anything good or bad about them. I guess that's a good thing. They made a 2.8 ltr 4 and a 3.5 ltr 5 based on the same design also.
Chrysler is rumored to be considering a straight 6, for some cars and trucks. For the chevy purist, it might not help, but still a straight 6
@@kierancarter8369 the 4.2l in the trailblazers are pretty garbage though. Make pretty pathetic power and have a ton of valve train issues. They lose oil pressure and wipeout bearings. I'd stay away from them if I were you the old stovebolt 6s are the way to go.
@@konnerkramer329 true that...lets just forget about that boat anchor
Yeah guys...all the inline builds you wanna do...I'll watch em'!!!
awesome numbers for that old 6.
I'd like to see what the spark plugs look like on #1 and #6 cylinders, see if they are leaning out. port injection would probably be a nice next upgrade.
1 & 6 are always lean guaranteed. There's no way around that without port injection
Straight sixes are torquey to begin with. This is incredible.
