Chrysler 413-440ci ''RB'' Block V8
Designed for 413-426-440ci Chrysler V8s that measure 8.75'' across block. Dual-plane design results in excellent low-rpm torque and outstanding high-rpm horsepower. Recommended for high-performance street and strip applications. Manifold is 1.7" taller than stock. Will not fit 1962-64 Max Wedge heads.Installation Notes:
Designed for street high-performance applications, Performer RPM cams provide power from 1500 to 6500 rpm. These hydraulic lifter camshafts are dyno-matched to Performer RPM manifolds for high-rpm horsepower while maintaining acceptable low-end torque. With 10 to 12 inches of manifold vacuum at idle, Performer RPM cams have more lift and duration than most street camshafts.
Performer RPM, Performer RPM Hydraulic Roller and Torker-Plus cams are for street high-performance and racing applications only - not for heavy vehicles. Use with Edelbrock Performer RPM heads (or other aftermarket cylinder heads), adjustable valvetrain components, screw-in studs, high-performance adjustable rocker arms and at least 9.5:1 compression ratio. Headers, high-energy ignition, lower-than-stock rear gearing and a high-performance torque converter are necessary.
Note: Adjustable pushrods or rocker arms required. For 1968 and later applications.
