The longer 833 input shaft uses the inner pilot hole of the early engine crank. Too long for gen 3 hemi. The Tremec with the Ford short shaft uses the outer crank register for pilot bushing or bearing on mopar similar to Ford.
Could the Ford TKX have gotten the shorter GM shaft?
Just quickly looking at my quick time bell for big block mopar to TKX measurements the shaft length is .090 less than depth of bell. The crank extends roughly an inch out of the block. The bearing is in that step. Should be good. Yeah I know I need to get the clutch and pilot bearing stuff bought and I would know.
I am getting nervous on bell issues. The QuickTime does look cooler than the Lakewood.
