Stock Magnum 5.2/5.9 camshaft w/carb?
just skimming through this, I thought I'd throw out that the original magnum cams don't have the nose for a mechanical fuel pump eccentric. You have to run and electric fuel pump or get the kit from Hughes (which has some complaints). Or........
Or....... you could get a cam from a 1989 or so LA 360. It's a roller cam and has the mechanical fuel pump eccentric.
