Alright my 84 CJ7 has a AMC 304 in it. My dads been harassing me about putting a 350 in it. I dont know whether or not to rebuild the AMC 304 or bite the bullet with the 350. Its got a 3 or 4 inch lift so it sits pretty high if that matters. Also leaning towards efi, any thoughts? Thanks
 
How you intend to use it should be your first consideration. When you put that thing in low range with any engine, the torque to the wheels is multiplied by the low range gear ratio. This puts a lot of load on either engine.
 
Take a look at the costs associated with the Chevy swap, it involves motor mounts, exhaust, radiator, wiring, Transmission adapter


The AMC 304 is a good motor, with a little more compression and a better intake manifold it would be a great combo

Also the bigger 350 will put more stress on the rest of your drivetrain, your AMC20 definitely would need 1 piece axles

Build a AMC 360 or 401 and it's a bolt in.
That bow-tie deal, ain't all it's crack'd up to be. ;)

AMC 360. Great engine & plenty of power. I had a 350 Chevy in my Jeep for 15 years and i went back to an AMC 360. Never looked back.
