Hey guys, I just contacted some people about stage III SPEC clutch and they asked me if I have LT1 or LS1. My plan (at this point) is to buy GM crate ZZ4 engine and bolt it up to the T56 that I already have.

Will SPEC clutch fit? If so, I think I should probably get LT1 version, but I need to be sure on this one.

 

If you have a LT1 T-56, you'd use the T-56 clutch and flywheel, and it will all fit fine. A LT1 flywheel will bolt right up to the ZZ4.

 

very cool, thanks.
