COMP Cams Camshaft C43 270H-R10

If you're looking to wake up your 1987-1998 Chevrolet or GMC 4.3L V6 engine that uses the non-balance shaft design, this COMP Cams Magnum 215/215 Hydraulic Roller Camshaft is a solid option. It's designed for mild street performance, giving you a noticeable, but not overwhelming, lope at idle that lets everyone know you've got something a little more serious under the hood. This camshaft is a great way to improve your engine's breathing and power output without needing to change out your stock torque converter, making installation a bit more straightforward.

This camshaft features a 215-degree intake and 215-degree exhaust duration at .050 lift, which is a popular choice for a mild performance upgrade. For best results, COMP Cams suggests pairing this camshaft with an aftermarket intake manifold, headers, and a gear ratio in the 3.40 to 4.10 range. These supporting modifications will help your engine take full advantage of the improved airflow and performance characteristics this camshaft offers. The hydraulic roller design means you get reduced friction and wear compared to flat tappet cams, contributing to a longer lifespan and consistent performance.

This camshaft fits a wide range of GM vehicles from 1987 through 1998, including popular models like the Chevrolet S10, Blazer, Astro Van, and C/K series trucks, as well as their GMC counterparts. It's important to note that this camshaft is intended for carbureted applications and is not CARB approved, meaning it cannot be legally shipped to California. Ensure your engine has the non-balance shaft configuration, which typically uses the same timing cover as a small-block Chevy V8.
