Right wiseco pistons are the reason the holes formed in the top, give me a break. They are harder pistons than Pro-X and actually a forged aluminum would have a higher heat tolerance, slightly, than a cast model so that was not your problem garanteed. Pro-X are fine under 70hp, they cant handle power. Why do you think that you can only get Wiseco's for Pro-X jugs, hhhmmm cause the Pro-X piston wont stand up in the big bore jug. |
