I know of a lot of them that use after market pistons whether KB's or others that aren't (both big and small block) than like long healthy, reliable lives on the street and the strip. None have the shakes like so many here try to lead you to believe will happen if you don't spend the $$$ to rebalance. Mine is one of the many. 'Course we aren't spinning unGodly high numbers either. 6-6200 tops is the norm.



Well thats what had me wondering I imagine over the years there has been thousands and thousands of 360's built and how many of them have been rebalanced. I want to spin mine to about 6500 In my build I'm just really curious how much of a difference I would see or I should say what the pros and cons would be
