Alright guys, I'm building a 37 chevy pickup with a 350 small block and a muncie m20. I am using a hydrolic clutch setup and it doesnt want to engage fully for me. The clutch slips like crazy. Ive been removing shims between the tranny and the bearing on the imput shaft but still no change in slippage. I was reading something about over stroking the throwout bearing. Is this true. What seems to be my problem.
