Here's a constructive tech question, something new, huh. The tired 140,000 mile 258 in my 85 CJ-7 will be coming out in the
next few weeks to be replaced by a rebuilt 258 out of an 80-81 CJ-7 (I need to take a look at the serial # to figure out the exact year).
Anyway, I figure it will be a direct bolt in replacement, but if anyone out there has knowledge of anything that won't match up
I'd appreciate it. Will still be using the same trans, for now. Hope also to use alternator, carb, ignition, etc. off of the 85 motor.
Well California will kick you in the butt for using an older engine. I think that everything will bolt right up, it wouldn't make sense for AMC to have redesigned anything important on an already succesful engine.
