I'm using the stock crank witha polish, stock rods, and wiseco 88mm pistons, pins, rings. Should I have it rebalanced? Just making sure before I spend another $225 at the machine shop :rolleyes:

Technically the rotating assembly is balanced based on stock everything, including the cylinder bore. So since you have 88mm pistons it's not exactly balanced. In reality, it depends on your HP goals. If you're going high hp then yes you should have it balanced.

Lol, Harry at Ztuner is tuning it for me. He's saying I'll have 375 rwhp on 93 octane and 450 on race fuel
