I have a ZZ4 that will be hooked to a T56 with a Weir Bellhousing. According to Weir I can use any standard flywheel for my engine. I am a little confused on exactly what I need. I've decided on the smaller flywheel. Pace Performance lists P/N 14088650, but does not mention the weight. I also need to know exactly which Centerforce II clutch will work with this setup. Every website lists their part numbers by make/model and I'm not sure which one would be equivalent to my setup. Thanks!

If you have a ZZ4 you can't just use any old flywheel. The ZZ4 has a one piece rear seal, and the flywheel bolt pattern is different(smaller circle) than the standard old Chevy flywheel bolt pattern. There is also a counterweight on the flywheel. I don't have a specific recommendation on size or any of that, but make sure you get a flywheel that will work with your engine!

Like BPOS said make sure you get the flywheel for the ZZ4. They did go to the one piece rear main in 1987. I did basically the same thing as you are doing. Fastburn 385 with a Muncie M21 trans. I don't have the part numbers handy but if you call Pace they will take care of you. That's who I purchased the motor and 153 tooth flywheel from. I have a Centerforce dual friction clutch. I ordered it from Jeg's and told them of the setup. Make sure that you know how many splines are on the input shaft of the tranny when you order. If you have any problem let me know and I can get the part #'s for you.
Good Luck

I found two flywheels for my ZZ4. One is the smaller 153 tooth 12 3/4" and the other is the larger 14". The guy at centerforce said that with the 355 HP a ZZ4 makes I need to go with the larger flywheel so that I can run the 11" clutch as their Centerforce II 10.4" clutch is not designed for that much HP. Is there a disadvantage to the larger flywheel/clutch? Is anyone running the Centerforce II with approx 350HP? What size flywheel do the new Camaros have?
