A caution on jeeps....the engineers had some funny ideas....like a little 3 speed tranny behind the big v8 and a then put a bullet proofT18 behind the 6 cyl....I dont get it...the one I would get is the 4 cyl one...they used a gm iron duke and 4 and 5 speed...same drive train as s10..when we were playing with jeeps years ago that was one to find as a Chevy 350 was an easy fit...
