I'm 17 years old and own a 1978 Chevy C-20 with a 350.I would like to know the easiest and cheapest way to change the trannies over.I have the transmission and most of the clutch components but I would like to know how to do it.I am going to build a 400h.p. 350 for it and pull it some and I already use it as my everyday truck.I just hate automatics.
