I have a 1965 barracuda and I am putting in a mag 360. It will be carburetor and electric fuel pump, short snout comp. cam. I have read a lot about HEI type distributors but I also understand they are tight under the hood. I think I am gonna use an electronic distributor from a 73’ duster, a gm 4 pin hei module, and a blaster coil. I’m confused do I need an msd ignition box as well? Also I saw something from pro form that is a distributor, module, and box? Like the idea it’s all inclusive. Wondered what others think? I know it’s been talked about a lot and once I felt I had a direction I’d read about another option. Thanks everyone. Gathering parts to put the engine back together.
