COMP Cams Camshaft C43 270AH-R14

If you're looking to get more out of your 1987-1998 Chevrolet or GMC 4.3L V6 engine, especially those without a balance shaft, this COMP Cams Magnum camshaft is a solid choice. This hydraulic roller camshaft is designed to wake up your engine, focusing on improving its mid-range and top-end performance. It's a popular upgrade for computer-controlled vehicles that are ready for more aggressive tuning.

This camshaft features a 215 intake duration and 220 exhaust duration at .050 inch lift, with a .435 intake lift and .455 exhaust lift. These specs are chosen to give you a noticeable increase in power and torque where you'll feel it most during acceleration and at higher RPMs. Because this cam is designed for performance, it requires supporting modifications. You'll need an aftermarket engine control chip to properly tune the fuel and ignition timing, a less restrictive exhaust system to help the engine breathe, and a torque converter with a mild stall speed to match the camshaft's power band. An adjustable valve train is also required to properly set up the valvetrain geometry.

This camshaft fits a wide range of Chevrolet and GMC vehicles, including popular models like the S10, Blazer, Astro, and C/K series trucks. When installing this camshaft, remember that it's intended for non-balance shaft 4.3L V6 engines. The timing cover on these engines is the same as the small block Chevy V8. Always refer to the manufacturer's installation instructions for specific details regarding setup and any additional components needed for optimal performance and longevity.
