My brother has a 68 Ford pickup, fully built 302 out of a police interceptor crown vic. Not very sure about his build, but he is having major problem getting started from a stop. I do know its a 3 on the tree, all motor, aggressive cam, and 4.11 gears in a 9". Anyone have any ideas other than maybe the clutch isn't big enough for it......and would it be better to have it dyno'd to see how much power it has if we have to change the clutch?
