Product Details
This COMP Cams Xtreme 4x4 Hydraulic Roller Camshaft, part number 12-413-8, is designed to fit a wide range of Chevrolet Small Block engines from 262 to 400 cubic inches, including popular applications like the 350 and 400. It's built to give your engine a noticeable idle and improved low and mid-range torque, making it a solid choice for street, off-road, and four-wheeling use. This camshaft is part of COMP Cams' Xtreme 4x4 line, which offers slightly more aggressive lobes than their original Xtreme Energy hydraulic rollers, focusing on usable power at lower engine speeds.
To get the most out of this camshaft, you'll need to pair it with headers, a gear ratio between 3.55 and 4.10, and a torque converter with a stall speed of 2000 RPM or higher. COMP Cams specifies that this camshaft is optimized for use with a melanized or nitrided distributor gear. Using a cast or steel gear without similar surface treatments will void the warranty. If you're working with an engine block from 1987 or newer that has provisions for roller lifters but currently uses flat tappet components, you may need a COMP Hydraulic Roller Lifter Install Kit for '91-'02 Blocks and an OE-style COMP Hydraulic Roller Cam.
This camshaft is a significant upgrade for those looking to enhance the performance of their classic Chevy V8. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding distributor gear compatibility and any other necessary components for a successful installation.
