I wasted a MP 533 and I have a MP 509 going on me now. I am looking into a different brand Cam also I have not made up my mind so I'll follow this thread also
ive done rockwell harness tests on cam cores their ok it was all the newer lifters that are a joke. most cam corps use all the same blanks for cams. all the good lifter corps are gone. crower makes nice stuff still
