COMP Cams Camshaft Kit CB XR308H-R12

When you're looking to get the most out of your Chevrolet Big Block engine, this complete camshaft kit from COMP Cams is a solid choice. You get the camshaft itself, a full set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure proper synchronization, assembly lube for installation, and decals to show off your upgrade. This kit is specifically designed for Chevrolet Big Block engines from 396 to 454 cubic inches that originally came with flat tappet camshafts.

This Xtreme Marine XR308H-R12 camshaft is built for performance, especially in applications like jet boats running with a B impeller and 10:1 or higher compression ratios, or for those hitting the river drags or bracket racing. The hydraulic roller design means less friction and more consistent valve lift compared to older flat tappet designs, which translates to better power delivery and improved engine response. The kit includes everything needed for the swap, making it a comprehensive solution for upgrading your engine's valvetrain.

This kit fits a wide range of Chevrolet vehicles originally equipped with these Big Block engines, including models like the 1967-1975 Chevrolet Bel Air, 1967-1973 Chevrolet Chevelle, and 1967-1974 Chevrolet Corvette, among many others. It's a significant upgrade for anyone serious about performance in their classic Chevrolet. Please note that this part is not CARB approved and cannot be shipped to California.
