Motor swap?

Ok I know I'm gonna hear some heat over this but I wanna know exactly what to do, my 258 is I think worn out hell it don't even run right. I wanna know what's easier to swap in a chevy V8 or a amc V8? I've got 37" boggers with a T-5 and the 258 and want...I mean need more power for the setup I'm about to build I don't think a 6 cylinder will turn 44" tires but whatever. Naw I just wanna know what's easier to swap into what I got?

It should be fairly obvious that an AMC V8 swap will be easier into an AMC Jeep than a Chevy V8 would be. Turning the big tires is more about your axle gearing than the engine. I'm assuming you're planning some 1-ton axles if you don't already have them and something beefier than a T-5...

Yes I'm getting one ton running gear, but man I'm having problems finding a amc v8, will it bolt right up to the t-5 or no?

Your t-5 is going to grenade with those tires and a v8! You would not ever be in a position to use the overdrive with those tires will you? Go with a heavier trans and save yourself some time to wheel instead of wrench

SBC = easier to get HP and torque, or at least cheaper.

AMC = easier to install and make work with Jeep drivetrain.

Pick your poison...

Take a look here for information on what works best with an AMC V8. There is a lot of good information about different engine/tranny setups at this site as well.

If you go with the chevy, I'll recomend M.O.R.E motor mounts. makes installation as far as locating your engine mindless. Worth the $ IMO. Going AMC will keep it pure blood.
