COMP Cams Camshaft Kit FC 299Th R7 Thumper

When you're ready to build a serious street/strip engine, this COMP Cams Big Mutha' Thumpr camshaft kit is what you'll want. What you get in this K-Kit is everything you need to get the camshaft installed and running right: the camshaft itself, lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, and even assembly lube. This kit is designed for Ford 351 Cleveland, 351 Modified, and 400 Modified V8 engines, and it fits a wide range of vehicles from the 1969-1986 model years, including popular models like the Ford Mustang, F-150, and Mercury Cougar.

This is a hydraulic roller camshaft with a 243/257 degree duration and a notably aggressive profile, giving it a very rough idle that lets everyone know you mean business. To make this camshaft perform at its best, you'll need at least 9.5:1 compression, a 2800+ RPM stall speed torque converter if you have an automatic transmission, and a good intake, rear gears, and headers. This setup is intended for serious street performance and strip use, so expect a significant change in your engine's character.

For a build like this, it's important to have all the right components. This kit aims to provide that by including the camshaft, valvetrain components, and timing set. Always refer to the included instructions for the most accurate installation details and recommendations for your specific application.
