Magnum gurus needed

Moparleo, the plan is to use the magnum front cover with serpentine belt system. On my parts list of things to get is the magnum alt/ac bracket and an ac bypass pulley. I will also be using an electric fuel pump and magnum-specific intake. The heads that were included with the sale are new stock replacement bare heads, and I will be purchasing springs to match cam.

Rustyratrod, that's kind of what I'm thinking. I will get contact info for machine shop that did work and see what they can tell me. Also, once I get it on the stand, will pull off oil pan for some better pics of crank. Definitely need to have full confidence in this setup before putting together.
