ok my dad wants to put a v8 into his 89 Yj, lifted 4" on 33 bfg mudders. we were either gonna do a 304,360, or chevy 350. hes leaning towards a 304 or 360 because we’ve heard they are simpler swaps than a 350. will the 304/360 bolt to the existing 6 cyl engine mounts? also will the radiator be big enough to cool a v8? finally will the ax15 bellhousing bolt up to the 304 or 360?

Thanks guys
Steve
