COMP Cams Camshaft Kit FF 283Th R7 Thumper

When you're looking to give your Ford Big Block a serious attitude adjustment, this COMP Cams Thumpr Camshaft Kit is the way to go. What you get in this complete package is a camshaft, lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, and even assembly lube to get you started. This kit is designed for Ford 429 and 460 engines, covering a wide range of vehicles from 1969 through 1978, including popular models like the Ford LTD, Mercury Marquis, and Lincoln Continental.

This isn't just a camshaft; it's a full system designed to work together for improved performance. The Thumpr series is known for its aggressive, choppy idle that really lets people know you mean business. It's a high-performance street cam that works well with a stock torque converter, but you'll see even better results with a 2000+ RPM converter and appropriate gearing. The camshaft itself features a 227-degree intake and 241-degree exhaust duration, which contributes to that distinctive thumping sound and helps your engine breathe better at higher RPMs.

Installing a camshaft kit like this is a significant job, often done when rebuilding the top end of the engine. It's a great way to wake up an older Ford Big Block and give it a noticeable power boost and a sound that stands out. Make sure to consult the included instructions for the best installation results and to ensure all components are properly seated for optimal performance and longevity.
