COMP Cams Camshaft Kit CS XE249H-12

If you're working on a Chevrolet Gen 1 Small Block engine, this COMP Cams Camshaft Kit is a solid option for an improved performance profile. This kit is designed for engines like the 305, 350, and 400 cubic inch V8s, and it works well with throttle body, crossfire, or carbureted setups. It's a popular choice for bringing older engines up to date or for a mild performance build.

Inside this kit, you'll find the XE249H camshaft, a set of lifters, and a complete timing chain set. The camshaft itself features a 206/212 degree intake/exhaust duration with a .495/.495 lift, which is a noticeable step up from stock without being too radical for street use. COMP Cams uses advanced lobe designs in their XE series to help the engine breathe better, especially at mid-range RPMs. This kit also includes assembly lube and decals to help you get the job done right.

It's important to note that this kit is for flat tappet camshafts and does not fit factory roller camshaft engines, which became common in many GM vehicles from the mid-1980s onward. You may need to remove the intake manifold or timing cover to confirm your specific engine's setup. This kit is not CARB approved and cannot be shipped to California.
