I have a 74 Duster and i am torn between getting a 06 Hemi 5.7 or rebuilding my 360. My machanic is telling me to go with the 5.7 but im not sure. I have seen good 06 5.7 hemi's engines, ecu harness, and transmission go for around $2500. Thats not bad, but my question is what all is needed to set the 5.7 hemi is the engine bay of a 74 duster? It doesnt sound like a bad deal unless there are thousands more i need to spend to get a hemi in my duster. Thanks for all the help
