Neo-Retro 327 - Modern V-8 Power with 327 Looks
While we were at it, we also installed a set of Comp’s Pro Magnum roller rocker arms. These rockers have rollers at the valve tip and the fulcrum to reduce friction, and the chrome-moly steel construction reduces flexing. We used 1.52:1 ratio, though 1.6:1 is also available to further increase net cam lift. We swapped valve covers to taller aftermarket pieces because we needed a breather provision, but the Pro Magnum rockers should fit under the Corvette covers, though other short covers with baffling may not have enough clearance.
