Dude,
Thanks for asking this question. I've been wondering about the CR vs. WR debate myself. It appears that you and I will have virtually the same motor (462 stroker, dual quads, etc.) from the Parhams. Will you be using an aluminum flywheel? I'm probably not (if I add one more costly goody to this engine, my wife will kill me). After riding in a few cars, I've decided on the CR with a 3.31 rear differential.
It doesn't really matter than much to me. Either combination is guaranteed to scare the hell out of me.
