I just got a 1980 CJ7 from my grandpa. The jeep was sitting in nothern california in the shrubs for 15 years. Its pretty amazing that there barely any surface rust on the whole thing. Its got a amc 360 with all the smog equipment taken off. Ive got the option to put in a 1982 258 4.2 carburated, or a 1993 Fuel Injected 4.0. Which engine is a better engine? Would the 258 be better than the 4.0 if it were fuel injected? What do you guys recomend?
