What size flywheel on T-56?
I have a T-56 on my 91 camaro Z28 that needs a clutch. Does anybody know what size flywheel it has?

Flywheels are not 10" or 11".
Flywheels are 12.8" or 14".
The ONLY flywheels that work with the T-56 happen to be 12.8".
It happens that the clutch disc diameter is about 10.4" in a T-56, maybe a little larger. Not 11". Doesn't too much matter, the WHOLE REST OF THE CLUTCH is completely different from any other clutch. A T-5 application clutch, for example, will NOT work.
Bottom line: doesn't matter what size the clutch is. Either it IS as T-56 clutch, or IT IS NOT a T-56 clutch.
If you need a clutch or flywheel, buy the one for T-56. It will be the size that it is. The ONLY size that there is and that will work.

It's also possible that he is using a T5 bellhousing with an adapter plate thus using stock hydraulic set up and flywheel/clutch set.

Right; IF AND ONLY IF it's not the LT1 version, since there's NO WAY to use that with the stock T-5 BH.
My comments were referring to the LT1 version. Kevin's comment is true.

Re: What size flywheel on T-56?
The dual-mass flywheel was a ZF6 thing, because they felt it would take out
the vibes better than a sprung hub.
Yeah, they are 11" not 10.5". I don't know why the thirdgens ran a 10.5" clutch. I'm running a thirdgen flywheel in my corvette with an 11" clutch. The bolt pattern for the corvette/lt1 11" stuff is the same as the T5 10.5" stuff.
