Carbed Magnum parts list?
This photo is a LA to 5.9 swap in a '79 Magnum.
My 5.9 Magnum LA swap used;
Edelbrocks RPM intake, 650 Thunder & electric fuel Pump for carb, local auto parts store fuel filter, Electronic distributor, (ignition to fire it up if your car is to equipped to do so, add cool and ignition, MSD or Chrysler box) Hooker headers.
If your car had a LA in it to start, use the OE motor mounts.
I deleated (took off) the A/C pump and used a shorter serpentine belt. I do not remember how many inches it was BUt it should be easy to look up at any auto parts store since it was an option not to have A/C. I used a oil relocation kit for my own self.
