Ahhh.... The bain of any Jeeper.... will one Jeep engine fit another Jeep application???? With the AMC 360 you're pretty safe as far as the engine goes. But you better make certain that the Mopar 727 will work without all the computer junk. It's going to be the '73s lack of electronics that's going to be the problem. You're going to have to swap the intake and exhaust manifolds for sure, front bracketry for the smog pump, and qute possibly the pulleys too. Jeep4x.com and Grandwagoneer.com is a great source for intormation. I've been down this road in the mixing and matching of Jeep running gear into a non Jeep vehicle. Lots of fun. Kept the axles, but ran with a non Jeep engine and tranny.
Yes you should be able to make this swap.
