LT1 to NV3500

[yeahitsbrown]

Hey guys, I was wondering if anyone knew where I could buy an LT1 to NV3500 conversion flywheel. I have a 94 shortbox 5 spd 350. I bought an LT1 to swap into it but I heard I can't use the flywheel off the TBI 350. The LT1 is externally balanced and the TBI is internally balanced I'm told.

Looks like the last post has some info.

What are you going to do for fuel injection? You cannot use the tbi intake on the lt1 due to the reverse flow cooling and a few other differences iirc.

I was gonna use the flywheel out of my truck but I was told the bolt patterns where the flywheel bolts to the crank are different. And a flywheel for a camaro has a different clutch bolt patterns. The LT1 6 spd cars have a reverse clutch system.

I'm using the LT1 manifold and injectors. Not using anything off the TBI.

Check the flywheel from your truck first, I believe it will bolt up fine.

But the LT1 is externally balanced. It needs weights on the flywheel does it not?

Where did you see the lt1 is externally balanced? The only sbc I know of that's externally balanced is a 400, but I'm far from an expert. As far as I know the short block is the same as any other 350. The differences are in the heads, intake an electronics....

Just what I read. I know there is at least one small difference. The water pump is gear driven off the cam. So there is a hole for the gear above the cam

Well idk then. You'll probably get a better answer to this question on lt1 or ls1.com. I would get a flywheel for whatever car the engine came from then order a clutch for your truck. If the pressure plate bolt patterns are different then just order a clutch for the same car. As long as the disk is 10 spline it will go on the 3500. Worst case you'll have to order the clutch disk an pressure plate separately instead of in a kit.
