Im looking at buying a 1979 Cj5 with a 304 that has no smog equipment on it. Living in CA that is an issue. I suspect the engine is toast and rather find a reasonable solution. Will a mid 80s CJ7 2.5l drivetrain fit in the CJ5? With most of the smog stuff this may be my likeliest solution. I'd like to assume the engine fits but I'd need different mounts. Not sure on rest re: length. or ability to use current trans/transfer case. Appreciate your input. (Or I obviously buy a pre 75.) Dont plan on much off road sompower isnt a consideration.
