I'm new to this site. I'm currently working on a 1972 Duster and installing a 5.7 Hemi from a 2004 Durango. I am building my own wiring harness from the Durango. Needless to say, I have a ton of questions but I will go through the archives before I start asking questions that may have already been answered. I purchased the Duster new in November 1972 right after I graduated high school. It has been a So Cal car until I moved to Washington 6 months ago so it is rust free and straight. My goal is to have it look like a "what if". What if a 5.7 was available from the factory in 1972.
