We were running a simular combo in our dragster. Ours was a 509 with Pro1 345 heads Brodix intake and a 1050 dominator. We pulled 820Hp. What we noticed with some cam swaps was huge gains and a few more by going to a newer dominator (gained 12HP from an old 1050 2 circuit to a new 1050 3 circuit) :wink:
