I have a 74 Dart sport, factory 318, 3 speed on the floor AC car I will be building with my son for a daily driver. I was thinking about trying to swap in a 5.2 magnum, with aftermarket fuel injection, and upgrading to an A833 OD trans. I would like to keep the factory serpentine belt setup and all accessories including AC compressor, has anyone made a complete swap like this to upgrade to the newer accessories? What would the best donor vehicle be? Will I need to grab all the modern AC equipment, or can I Frankenstein it with the original controls, condenser, radiator etc?
