COMP Cams Camshaft Kit CB XS290S-10

This is the COMP Cams Xtreme Energy Camshaft Kit, specifically the CB XS290S-10 model, designed for Chevrolet Big Block engines like the 396, 427, and 454. If you're building a pro-street or bracket racing machine and want a noticeable bump in performance, this kit is a solid option. It's designed to work with engines originally equipped with flat tappet camshafts, and it's a popular choice for those looking to get more out of their big block Chevy.

What you get in this kit is everything you need to get the camshaft installed and running: the camshaft itself, a set of lifters, a complete timing chain set, assembly lube to get everything properly lubricated during installation, and decals. The camshaft specs are 252 degrees of intake duration and 260 degrees of exhaust duration, with a .495 inch lift on both intake and exhaust. This profile is meant for a street-driven car that also sees track time, but it really needs good supporting modifications like an upgraded intake manifold, headers, and a torque converter with at least a 3500 RPM stall speed to really shine. It's a well-built kit that COMP Cams is known for, giving you confidence in your engine build.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance, ensure you have the necessary supporting modifications in place, as this cam is designed for a more aggressive setup.
