    These camshaft / lifter kits are perfect for use with BBC 477 to 496 with 4.25" stroke with OEM 188 or 990's ProMaxx or RHS 320s. Max rpm 5800-6200. For those of you that go old school and want to use the legendary GM Square Ports this is your cam. Welcome to the brotherhood of BBC that make 600HP and 600#/ft. on pump gas! This cam will also work with the listed aftermarket aluminum heads. Single plane intake would be your best choice, and you will not sacrifice any torque. Carb of choice is a 950HP 4150. 2" headers are recommended. Be sure to have the car washed because when you pull into cruise night everybody will turn their heads. Will show no mercy on manual transmission. Good with power brakes. 850 Idle RPM
