COMP Cams Camshaft C43 266H-R12

If you're working on a '87-'98 GM 4.3L (262 cid) V6 engine that doesn't have a balance shaft, this COMP Cams Magnum Computer Controlled camshaft is a solid option for improving its performance. This hydraulic roller camshaft is specifically designed to work with throttle body and sequential port injection systems when paired with an aftermarket computer chip. It's known for delivering good gains in both the low end and mid-range power bands, making your truck or SUV feel more responsive in everyday driving.

The C43 266H-R12 camshaft features a 210/215 duration at .050 lift, which is a popular choice for these engines when seeking improved torque without sacrificing too much drivability. Keep in mind that installing a camshaft like this typically requires an adjustable valve train setup to ensure proper tuning and operation. The non-balance shaft 4.3L engines from this era share their timing cover with the small block Chevy V8, which can be a helpful detail during installation.

This camshaft is a significant upgrade for your 4.3L V6, offering a noticeable improvement in performance. 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 details on required components and procedures.
