COMP Cams Camshaft Kit OL 287T H-107 T

If you're looking to give your Oldsmobile V8 a serious performance boost, this COMP Cams Mutha' Thumpr camshaft kit is a solid choice. It's designed for street and strip use, aiming for a noticeable increase in power. This kit is built for Oldsmobile 260, 307, 350, 403, 400, 425, and 455 cubic inch V8 engines, covering a wide range of applications from 1967 and newer, including popular models like the Cutlass Supreme and Electra.

This isn't just a camshaft; it's a complete package to get you running. Inside the box, you'll find the camshaft itself, lifters, valve springs, retainers, valve locks, and valve stem seals. COMP Cams also includes a timing chain set to ensure your timing is spot on, plus assembly lube for flat tappet applications and decals. To get the most out of this cam, you'll want at least 9:1 compression, a 2500+ RPM stall torque converter, an upgraded intake, and headers. Expect a rough idle, which is typical for this kind of performance camshaft.

When installing this kit, remember that it's intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. It's a significant upgrade that will change the character of your engine, so be prepared for a rougher idle and ensure your supporting components are up to the task.
