4.7 engine swap help
I have a 2002 with a 4.7. Engine has head gasket issues and 187,000 miles on it. Got it cheap, with the intent of fixing the head gasket issues, for now-it runs great, then swapping out the engine in the spring. I've read around the forum and researched other sources, only to find different answers to my questions. Noone seems to know for sure.

Since low mileage 4.7's are hard to find at a good price, i think i'm going with a 5.7. I need to know if anyone knows for sure, or if there is a website i can go to for interchange info, like, what years are interchangeable, and, what models? Jeep, Durango, Ram? And, what needs to be changed over? I know I'd need a 5.7 wiring harness and ecu, and 5.7 motor mounts. Anything else?

Any help would be greatly appreciated....thanks

More than few people have done this swap successfully. A search for 5.7 swap or hemi swap will probably find what you are looking for.
