I'm swapping a set of Pro Comp victor knock offs on my 426 Wedge and I'm wondering if I'm going to have to run into problems with detonation. The motor is .070 over and has kb237s .025 in the hole. The heads are 72ccs and the cam is a Voodoo 60304. The compression calculator I used said 12.2 to one! Anyone have ideas or experience with a combo like this on pump? With the old 452s I never had any problems, but I'm a little concerned I might hurt the pistons.
