Chevy 496 Comp Cams Roller Rockers Valvespring Upgrade Steel Rocker Arms
|
We opted for Comp's 1.7:1 ratio steel rocker arms (PN 1320-16). These are a tad stronger, which would attribute to less flex and more control when the spring began to float the valve. Pro Magnum roller rocker arms combine the strength of 8650 chrome-moly steel with the weight savings of aluminum rockers. Comp cut weight in non-critical sections and added strength to the areas where the rocker endures the most punishment. View Related Article
