Greetings all, I've searched and can't seem to get a definitive answer and I just want to make sure before I start buying parts. I'm working with a LS3/T-56 build and someone is offering me a new LS1 SPEC Stage 3 clutch for really good deal. I just want to make sure that an LS1 clutch will work with the LS3 as long as I also use an LS1 flywheel. Can anyone confirm this? Thanks in advance!

 

If the bellhousing, clutch and pilot bearing all match, you can run the LS1/6 style clutch and flywheel.

 

You will need to use the ls1/ T56 pilot bearing( deeper location in the crank).
Not the larger diameter LS3 / TR6060 bearing that sits more outward in the crank.
