Product Details

This is the COMP Cams Xtreme Energy 212/218 hydraulic roller camshaft, part number 08-412-8. It's designed for mild performance upgrades on Small Block Chevrolet engines built from 1987 and later that came with factory roller camshafts. This camshaft is a solid choice if you're looking to improve your engine's mid-range power without going too radical, and it works well with rear gear ratios in the 3.23 to 3.73 range. You can expect a slightly noticeable idle with this cam, which is common for performance hydraulic roller grinds.

The Xtreme Energy series from COMP Cams is well-known for providing a noticeable bump in performance, and this particular grind, the XR264HR-10, balances power gains with drivability. It's built for OE roller SBC applications, meaning it's intended to work with the factory lifters and valvetrain components in many Chevrolet and Buick vehicles from the late 80s through the 90s, like the Chevrolet Camaro, Corvette, or Buick Roadmaster. While it offers improved performance over stock, it's still considered a mild upgrade, making it suitable for daily drivers or street rods that see regular use.

When installing this camshaft, it's important to ensure your engine is properly set up for a hydraulic roller camshaft. This includes having the correct lifters, pushrods, and valve springs. COMP Cams recommends checking their specific valvetrain requirements to match this camshaft for optimal performance and reliability. This camshaft is not CARB approved and cannot be shipped to California.
