I have a ‘66 200 block with a C4 behind it right now, but have a T-5 waiting in the wings to take over. Is there much of an advantage to using a 9” clutch vs. a 8 1/2”? I have a 63 bell housing and a flywheel for the 8 1/2” (Dog dish) that was used on the run stand for engine break in. But if the 9” is the preferred way to go, I’ll go that route instead. I’d like to use a hydraulic clutch also.
