Building the World's First Carbureted GenV LT1 Stroker Engine (We Think!) with Gibbons Motorsports

[@johnbrewer4619]

Love your videos!

[@TheHorsepowerMonster]

Hey, thanks a lot! And thanks for watching!

[@racerd9669]

You may want to retract your advice about using the stock injectors to plug the holes in the heads. I have do this on a LNF Ecotec because I converted it to port injection. After driving the car less than 1000 miles it burnt the centers out of the injectors. The injectors are cooled by the fuel flowing thru them, so my advice do not use the stock injectors as plugs.

[@jareknowak8712]

True. In Europe there are many GDI engines converted to LPG fuel. LPG fuel uses separate injectors (MPI), but You have to run some normal gas (10-15%) thru direct injectors just to cool them down.

[@Lance.West4]

Good advice to have thanks.

[@LT3Fluffy]

Would it be OK if he wasn't planning on using the injectors again or will the burnt injector drop stuff into the cylinder?

[@Lance.West4]

@@LT3Fluffy sounds like it will burn the tip of the injector, because there's no liquid flowing to keep it cool. Once it burns through a little it doesn't take long to start cutting into things like a torch.

[@racerd9669]

@@LT3Fluffy No , it burns the center out of the injector and leaks compression out side.

[@tiggerjay2k6]

It is absolutely okay to put a carb on a modern block. I love it. Badass no doubt.

[@jessemurray1757]

Very cool and definitely different. I have a supercharged LT1 myself, so I love this. However, I am left with a few strong opinions which I'm sure you and many feel the same way about, but it has to be mentioned. Direct injection, variable cam timing, squirters and high compression are essentially what makes the LT1 what it is, now gone. Also, the same combo retaining those items would make a bit more power, probably closer to 675. In fact, with that cam, compression could have been even higher than 11.5:1. Lastly, that is a very expensive way to build a carbureted 417 cube engine. A stroker LS 6.0 or 6.2 with LS3 heads would make the same power but could cost quite a bit less. Anyways, I digress, it's still very cool to see it done and I'm glad you covered it. Keep up the good work as always!

[@frankmc5112]

I got to agree. Just because you can doesn't mean you should. Sure, it's neat, but so is the video of the guy that did reverse flow heads on a SBC with the exhaust coming out of the intake ports. Most of the the power of this motor is from the cam. I'm sure Gibbons asked themselves "why?" when they were asked to do this, but realized the old bastard wanting this stupidity had plenty of money. Plus, why not make a video too. Still props to the guys pulling it off. It is at the very least interesting.

[@josephwilliams7180]

You hit the nail

[@xxdabroxx]

I was thinking you could do a lot better with an olds school SBC with a lot less custom stuff. I don't have dyno numbers to back me up but I'll bet my 383 makes more that this put out (13.5:1 though). Longevity of this build is likely better, but I know I've got a lot better oil pressure. I'd sure take the block stiffness that the new engines have though.

[@Motoinc]

If strokeing means blocking off the piston oil squirt , i would save the oil squirter and choose another way to make power. Oil squirter is a must have in ANY build IMO

[@jasonhowell9589]

When they say stroking a motor it means you're adding more throw to the crank longer throw the reason they had to get rid of the oil squirters is because now that the crank has a longer distance to go it comes higher up and would actually hit the oil squirters at the bottom of the block that's why the squirters were removed

[@jasonhowell9589]

Take for instance an old school Chevy 350 block they would stroke it by taking a 400 crank and rods and putting it into the 350 motor essentially giving you a 383

I also appreciate all the details you give throughout the video. Very well done. One thing I would comment is about the compression… I would not be concerned with the factory 11.5:1 compression ratio with the carburetor. With 93 octane fuel and the camshaft that was chosen, that would have worked great IMO. I built an LS3 based 349 cube de-stroked, carbureted engine that makes 600HP and has 12:1. It’s in a Nova with a 6 speed. No problem on pump gas. Keep up the great work!

That's why IMO old school will never die;you just proved it can work with modern engines. Guys did you know the 417 CID you got out of this engine build is similar to the old 6.9 liter (417 CID) Mercedes Benz V8? They were used in NA up to '79 and were a torquey V8.

The thought of slapping a carb on an LT1 should be an anathema to anyone with half a mind for how modern engines were designed to operate. What the LT1 or LT4 really needs is port injection to clean the intake valves in addition to keeping the computer controlled direct injection. Hey, GM did that with the 2019 ZR1 LT5 motor. That would at least be a real engineering exercise. “Hell, let’s slap a carb on it!” SMH Great, another informative and educational episode of POWERNATION.

The builder should have been aware of the paint on the PaceSetter Headers.

This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high-heat paint or coating designed for use on headers be applied.)"

So much so I opted for quad 50mm throttles on my new tarmac rally motor vs 48mm dellorto's. But regards the build detailed here. The customer gets what the customer wants. If they're happy with the results. That's all that matters. Jordan

[@e36blur]

EFI is safer, but with sensors constantly breaking, I'd argue carbs are way more reliable. The carb will get you down the track the same way(within reason). EFI will pull timing if it senses anything wrong, and as far as I know, efi systems dont detect broken sensors. Which will probably change in the future. Right now its a crapshoot. The one major advantage efi has over car in my opinion is for HPDE environments and drifting, where a normal carb will starve of fuel unrelated: carbs sound better than EFI

If he's comfortable working with carburetors. It's really not any different than taking a small block from the 60s or 70s and putting fuel injection on. Personally, I do love the carburetor cuz you don't have the electronic engine control module to go out. They will go out at the most inopportune time and place. You have to really work hard to break a carburetor. While I do love the modern makeover the old reliable small block and they made great improvements. And yes, fuel injection and computer-controlled ignition can be made to do wondrous things. I still love the old school simple dead reliable 4 barrel.
