Default Ls1 flywheel question
I bought a ls1 engine out of a 04 Gto with out a flywheel. I have one flywheel I know is out of a 6.0 ls truck motor. And one that is 3/8 thinner than the truck one. The question is what are stock ls1 Gto or camaro flywheel specs. I want to use the right one Thanks

What did the 3/8 thinner one come out of? I would bet it would be right, as trucks normally come with heavier flywheels.

The guy I got it from said a ls1 camaro. But you know how that goes. Its definitely lighter,thinner and would make a huge difference in the through out bearing spacing. I'm sure someone here knows the info I need.

Thanks

The auto trans flex plates are light and thin. I wonder - do you have a T56 flywheel in one hand and a 4L60E flex plate in the other hand?
