Product Features:

• Best with aftermarket torque converters and 9.5:1 compression.
• Great high RPM power.
• Easy on valve train parts.
• Can be used with mild ratio rocker arms and traditional performance valve springs.

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts.

Product Features:

• Excellent performance in street carbureted applications.
• More vacuum allows an increase in duration for improved performance and assists power brakes.
• Quicker opening lobe profiles deliver increased responsiveness and more area under the lift curve.
• Best performance with aftermarket intake manifolds, headers, lower gear ratios etc.

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.
