Product Details

This COMP Cams Classic Thumpr camshaft is designed for the Chrysler 392 HEMI engine, specifically for high-performance street applications. You're getting a hydraulic flat tappet camshaft that's built to give your engine a noticeable, choppy idle that's characteristic of the Thumpr series. It's engineered to work with a stock torque converter, but you'll see improved performance with a 2000+ RPM stall converter and appropriate gearing.

The camshaft features a 227-degree intake duration and a 241-degree exhaust duration, a common setup for street performance that balances power with drivability. This profile is a popular choice for enthusiasts looking to add a distinct sound and improved performance to their classic Mopar vehicles. While it functions with a stock converter, pairing it with a higher stall converter and suitable rear-end gears will unlock its full potential for acceleration and responsiveness.

This camshaft is intended for performance street use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built component for those who want that classic Thumpr sound and a noticeable bump in performance for their 392 HEMI.
