I am normally a toyota guy, but I have the chance to buy a 1970 CJ-5. I am gonna put a 350 in and spring it over if I do get it. I believe it has dana 44's already. What does it have to transfer case, transmission and will a 350 fit in fairly easily(room wise) and with the existing tranny or will i have to swap. If I do swap it would be to a sm-425. it has the 4 banger in it right now and the 3-speed trany. Please elighten me.
