Regards compstar, I ran them for years in a motor that saw 7500 every pass, current owner still has them in the motor.
I ran them on the advice of Chuck at Best Machine, who built that motor. He had high praise for them in that price segment.
Just relaying my experiences. Those wise asses who cast stones always do.


this is the kind of stuff i want to hear about. Just as someone mentioned 440 Source, i've physicly seen the aftermath of their rods breaking at only 7000 rpm & high 600 HP & it was rod failure, nothing else. I am seriously thinking Compstar but just thought i'd test the waters & see what others might suggest. Thank you for your input.


Give Best Machine a call and see what those guys recommend. They have never steered me wrong, and always been top shelf in both knowledge and skill.
