Edelbrock Camshaft Performer RPM Hydraulic Roller SB Chevrolet 1955-1986 Wide-Center EFI

If you're looking to get more torque out of your small-block Chevy, especially in the low to mid-range, this Edelbrock Rollin' Thunder camshaft is a solid choice. It's designed for daily drivers, trucks, vans, and 4x4s that operate from off-idle up to about 5500 RPM, and it's a popular upgrade for vehicles like the Chevrolet C10 pickup, Chevrolet Bel Air, and Avanti II.

This camshaft features a hydraulic roller design, which is known for its smooth operation and reduced friction compared to flat tappet cams. With an intake duration of 262 degrees and an exhaust duration of 266 degrees, combined with a .628-inch intake lift and .608-inch exhaust lift, it's built to significantly improve throttle response and overall torque. Edelbrock suggests matching this cam with their Performer manifolds for the best results. When paired with specific components like the Pro-Flo XT EFI system and RPM E-Tec cylinder heads, this cam has shown impressive performance figures, producing up to 440 horsepower and 425 ft-lbs of torque.

Keep in mind that this camshaft requires a high stall torque converter and stock ratio rocker arms. It also includes flat tappet lifters, assembly lube, and instructions to help with installation. Please note that this part is not CARB approved and cannot be shipped to California.
