Smallblock Pistons: 1 question.....KB's -or- Sealed Power(SpeedPro hypers)???

A lot of guys have gone pretty quick with the Hypers. 11’s are nothing for these slugs. I suggest pay close attention to the tune. But then again, that should be a basic thing no matter what your running.

I have used both slugs with no issues. In this case, cheaper is better.
