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...

I'm going to run at least 5.13 gears, and this thing is gonna be for full blown offroad like trailered anywhere I go not highway driven. I'm wanting to find a t-18. But what is gonna have to be done to swap in a amc v8?

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.
