8480016 & 818017 - Long Slot Rocker Arms for Small Block Chevrolet - Accepts 7/16" Dia. Rocker Stud/Heat Treated Stamped Steel Construction/Available in 1.5 or 1.6 Ratio
With most claimer rules prohibiting the use of roller rocker arms, racers are constantly looking for a better O.E. style rocker that will handle the higher valve lifts and r.p.m.'s. For the Small Block Chevy the weak link seems to be the 3/8" dia. rocker stud that will not hold up. Because stud girdles are sometimes disallowed some races are installing "beefier" 7/16" rocker studs and machining the stock rocker and ball to accept the 7/16" stud. This is a time consuming task and is not always performed to precision specifications which can cause rocker arm galling and possibly greater damage to the engine. These new stamped steel rocker arm kits feature rockers and balls that are precisely engineered at the factory to accept a 7/16" dia. rocker stud without any machining. The rocker arms are special heat treated for endurance and have long slots for increased net valve lift. Hardened grooved rocker balls and self-locking nuts are included. NOTE: Due to the intended use and material limitations, these parts are not warrantied after installation. Recommended maximum spring pressure is 350 lbs. Always insure adequate oil pressure to the top end for extended rocker and spring life.
