COMP Cams Camshaft Kit FS 291Th R7 Thumper

If you're looking to wake up your Ford small block engine, this COMP Cams Mutha' Thumpr camshaft kit is a solid option. It's designed for Ford 221, 255, 260, 289, and 302 cubic inch engines, covering a wide range of classic Ford vehicles like the Mustang, Fairlane, and Torino. This kit is built for street and strip applications, aiming to give you a noticeable bump in performance, especially when paired with other supporting modifications.

This isn't just a camshaft; it's a complete K-Kit, meaning it includes everything you need to get the job done right. You'll find the camshaft itself, a set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure your valvetrain stays synchronized, plus assembly lube and decals. COMP Cams designed this camshaft for engines with at least 9:1 compression and recommends pairing it with a 2500+ stall torque converter, an upgraded intake, and headers to really let it breathe. Expect a rougher idle, which is characteristic of performance cams like this, but it's a trade-off many enthusiasts make for the improved powerband.

Installing a camshaft is a significant job, and this kit aims to make it as straightforward as possible by including all the necessary valvetrain components. Remember to consult the included instructions for the best installation practices. This kit is a popular choice for those building a performance street or strip engine and looking for that classic muscle car sound and feel.
