These camshaft / lifter kits are perfect for use with SBC 400 to 427 CID Air Flow Research 220-235 heads. Max power 6300 rpm, Peak torque 3500. This cam was designed for 1.6 ratio rockers to be used with the AFR heads. The increase lifter velocity maximizes the fill rate of these heads on large stroke engines from 3.75 to 4.00". The cam will maximize RAM Effect and fill cylinder for increase VE. Use of 1.750" on engines up to 412CID and 1.875" on engines over 412CID is highly recommended. We recommend a 3200 stall, a 850CFM carb, and a minimum of 10:1 compression.
