I'm going to be installing a BBC 475ci, about 550hp. I'm going with the zz572 wire looms, now, what do i use for wires? I have a pro-billet dist(non-hei), heddman elite headers. What angle boot should I get? Straight? I'm think of getting a pre-cut set. Any suggestions? Anyone have a part # for the ZZ572 plug wires? If figure if I'm using the looms, the wires to match would be good, Thanks!
