I "know a guy" with a Dodge 360 in a CJ5... Me. Problem is I can't offer you much in the way of advice on the swap as it was done by a PO and I just got the Jeep in Jan. It has a Torqueflite 727 trans and the original Dana 20 transfer case. Strong running engine but I only get like 8 MPG with 4.88 gears and 33s. It's an older engine with a Holley 4 barrel headers, and MSD ignition. Supposedly, the full width Dana 44 and 9.25 axles came out of the same truck.
