COMP Cams 11-600-20 - Nitrided Camshaft CB 279T H7

Thumpr NIT 227/241 Hydraulic Flat Cam for Chevrolet Big Block 396-454

High performance street, stock converter ok, best with 2000+ converter and gears. Choppy/thumping idle. Nitrided.

Designed to deliver an aggressive, hard-hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods, the Thumpr series' early intake valve opening and long exhaust duration create optimum overlap for that race car idle. The Thumpr grinds all require an aftermarket torque converter and lower gear ratio to ensure the drivetrain always puts the engine in its powerband. Additionally, Thumpr camshafts typically deliver reduced vacuum at idle, making a vacuum canister, pump or hydroboost a requirement for vehicles running power brakes.
