COMP Cams Cam & Lifter Kit OL 287T H-10

If you're looking to give your Oldsmobile V8 a serious performance boost for street and strip use, this COMP Cams Mutha' Thumpr camshaft and lifter kit is a solid choice. This kit is designed for engines like the 260, 307, 350, 403, 400, 425, and 455 V8s, fitting a wide range of vehicles from 1967 onwards, including popular models like the Oldsmobile Cutlass and Buick Electra.

This kit includes the OL 287T camshaft and matching hydraulic flat tappet lifters, along with assembly lube, decals, and instructions to get you started. To really make this cam shine, you'll want to pair it with at least 9:1 compression, a 2500+ RPM stall torque converter, a good intake manifold, appropriate gearing, and headers. Expect a noticeable improvement in performance, especially at higher RPMs, but be aware that this cam is designed for a rough idle, which is part of its aggressive street/strip character.
