Im not sure this guy is a racer, budget minded yes, racer probably not. He at best is a STREET/strip guy, hence the 3000 miles. It would take me many many years to put 3000 miles on my race car. As for the balancer, ive heard other companies(not just 440source) having problems with balancers. People say they put thing on the "correct" way, businesses say theres no way you did. Its a he said she said kind of thing. Im guessing that the summit, jegs, 440source balancers all come from the same place, they all look the same at least. Im not sure I would go cheap here either, but im not bashing 440source for a part with 3k miles on it. Ive seen "good" rocker arms not make it 10 runs before causing some serious damage on a motor and they werent cheap either. Ive seen "good" engine shops who are sponsors of the site build motors that didnt make it 3 passes. [Edited by Moparts - Keep it clean] happens, then we move on and rebuild, right?
