- 83 CJ8, 304 vs, automatic, stock besides motor.
Having a hard time finding anyone who can give me a definite answer on what flexplate I need to go from a 72 amc 360 out of a wagoneer to my 904 tranny in my CJ8 with the AMC 304 in it. Finally found someone who seemed to be very knowledgeable on the swap. He said that on an amc 360 that old, that I would have to grind the crank about a 1/4 of an inch to make it fit the 904, or it would eat flexplates. Would I be better off to grind the crank, or find a different automatic Transmission , such as a GM Turbo 400 ? Is the 904 or the GM Turbo 400 a better Transmission ?
