Product Details
If you're building a high-performance street or strip machine with a Chrysler 383, 400, 413, 426 Wedge, or 440 engine, this COMP Cams Mutha' Thumpr camshaft is a solid choice. It's designed to give you that aggressive, rough idle and strong performance feel that many enthusiasts look for in these classic Mopar V8s.
This camshaft features a 235/249 degree duration at 0.050 inch lift, which is a pretty aggressive profile for a hydraulic flat tappet cam. To get the most out of it, you'll want to pair it with at least 9:1 compression, a torque converter with a 2500 RPM stall speed or higher, a good intake manifold, rear end gears, and headers. It's built to handle the demands of spirited driving and occasional track use, offering a noticeable change in how your engine performs.
Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. It's intended for off-road or competition use where emissions regulations may differ. Make sure your engine is set up to handle this kind of performance camshaft for optimal results.
