let me explain my screen name, and introduce myself.

my horrible build plans: Swap in a 4 speed, late-model 360, dana 60, and paint it (GASP! the horror!) Hugger orange. (a GM color)
I was completely on board till you mentioned the paint. But I've wanted $600 to buy a gallon of the Camaro Synergy Green, so I'm not judging. But I do have to ask. Why a dana 60? Are you gonna have two superchargers on it or something? I'd go 8-1/4" (if it's built right!) or at most a 8-3/4"
