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




If the cam 's hardness is good but the lifters aren't then why does the cam lobe fail and not the lifter?


cam/lifter falure starts with metal transfer from lifter to lobe, like pepper grain size then cam acts like lathe and cuts them both to death


MOPAR OR NO CAR
