COMP Cams Camshaft C43 266H-R12

Starting with a 210/215 duration at 0.050 inch lift, this COMP Cams Magnum Computer Controlled hydraulic roller camshaft is built for Chevrolet and GMC 4.3L (262 cid) 90-degree V6 engines originally equipped with a flat tappet cam. This camshaft is designed to work with throttle body (TBI) and sequential port injection (CPI) systems, provided you are using an aftermarket engine control chip. It’s a popular choice for those looking to get more out of their engine, especially in the low-end and mid-range power bands.

This camshaft is a retro-fit hydraulic roller design, meaning it allows you to upgrade from a flat tappet system to a more efficient roller setup. Roller cams generally reduce friction and wear compared to flat tappet designs, which can lead to improved performance and longevity. The specific lobe separation angle and lift profile are chosen to provide a noticeable improvement in torque and acceleration where you'll feel it most during everyday driving and towing.

This camshaft is compatible with a wide range of Chevrolet and GMC trucks and vans from the mid-80s through the late-90s. While it’s designed to work with factory injection systems, remember that an aftermarket engine control chip is required for proper operation. This is a significant upgrade for your V6 engine, offering a solid increase in performance without requiring extensive modifications.
