Edelbrock Perf RPM Cam and Lifters Kit Pontiac 350-455

This is the Edelbrock Performer RPM Cam and Lifters Kit, part number 7157, designed specifically for Pontiac 350 to 455 cubic inch V-8 engines. If you're looking to improve your classic Pontiac's performance for street applications, this kit offers a well-matched combination of a hydraulic flat tappet camshaft and lifters that work together to increase power across a broad RPM range.

Edelbrock dyno-tested this camshaft with their Performer RPM intake manifold and cylinder heads on a 455 engine, achieving notable gains of 422 horsepower and 441 ft-lbs of torque. The camshaft itself features 231 degrees of duration at .050 lift on the intake side and 240 degrees on the exhaust, with .470 inches of lift for both. This setup is engineered to provide strong performance from around 1500 RPM up to 6500 RPM, while still maintaining about 10-12 inches of manifold vacuum at idle, which is important for street drivability. The 113.5-degree lobe separation angle and 112-degree intake centerline contribute to its street-friendly characteristics.

This kit is a solid option for Pontiac owners looking for an improved power band for their street machine, fitting a wide range of vehicles from the 1950s through the late 1970s, including popular models like the Firebird, GTO, and Grand Prix.
