I was considering swapping 4.0 for a 302, decided to build the 4.0 instead. any recommendations on mods? Just sent it out for machining, .030 over, not sure on the milling trying to get the compression up to 10.75- 1. High compression pistons, thinking supercharger and camming it. I have looked at several places for rebuild kits, seals, gaskets, bearings. Any advice would be appreciated.
