Would a LS T56 bolt to a BBC 502? Ok so I'm selling my LS1 T56, LS2 flywheel and clutch on Ebay, I had a question regarding my trans,clutch and flywheel working on a 6th Gen BBC 502?
Would it work and if not why? I searched a little and read something about the LT T56 working because of the input shaft?
Thanks,
Josh

Both will work:
The LS1 trans just needs a flywheel that will adapt it, dont know what flywheel but that is all it would need:
The LS1 trans will work with :
The adapter bellhousing and the pilot bearing sxtension.
The LS1 trans uses a plate that adapts and uses a T5 bellhousing so you can use whatever clutch and pressure plate you want as long as it is a 153 tooth wheel.
the LS1 might be easier to use but the LT1 trans might be near impossible to get a flywheel to work unless the stock LT1 style flywheel will bolt to it and be the same balance as the engine.

Theres a company in Mass. Called Fortes performance, that makes a kit. the Ls1 6 speeds will bolt up with adapters. ( you actually swap to an old school 4 speed Bell housing. if you use an Lt1 trans you need to replace the input shaft with the Ls1 input shaft ( its longer to make the reach when converting to a 4 speed bell housing...at that point you use your external balance flywheel and a clutch to match. hope that helps

I just did the swap you are asking about.I have a 454 not a 502.I used my stock flywheel, a centerforce clutch set-up,a lakewood scattershield(only because I had it) and a adapter plate from "the gearbox".You do need a ls-1input shaft if using a lt trans.Pretty simple bolt together gig.You do need the longer pilot bushing.Hope that helps...

Not sure if you got your answer or not so I'll throw my .02 in.
LTx T56 will bolt up directly to any SBC/BBC as long as it's a one piece and the flywheel is balanced properly. You can bolt it up to a 2-piece, but you have to have 2-piece flywheel that will work with the LTx. McLeod, Findanza, Centerforce all make one.
I run a Gen V 502 block (1-piece), but it's been stroked and at the time only 2-piece 4.25 cranks were available so I have to use an adapter to adapt the crank to the block and a different flywheel to adapt the 2-piece crank to my LTx T56. If I was able to get a 1-piece 4.25 crank I could have just bolted everything up and saved some $$.
LSx T56 will bolt up but you need to use a different bellhousing because the bolt pattern and input shafts are different. Same flywheel issues as before.
Also remember that a LSx and LTx use different clutch hydraulics and function differently. LTx is a pull type clutch and LSx is a push so make sure you think of everything you need.
