85-88 Competition Cams Roller Tip Rockers

Competition Cams Magnum roller rockers offer an accurate 1.52 rocker ratio. Stock stamped rocker ratios can vary from 1.46 to 1.50. With Magnum Rockers at 1.52 it effectively increases a standard .420 lift cam to .432 lift. With the increased lift and the friction reduction at the valve horsepower increases and rev's are quicker. Must install new pushrods to validate manufacturer's warranty.
