What type of lifters does this camshaft require?

This is a hydraulic flat tappet camshaft. It is designed to work with flat tappet lifters. If your engine block has factory provisions for roller lifters, you will need to confirm compatibility or use a specific roller lifter kit.

Does this camshaft fit my 1990s Chevrolet truck?

This camshaft fits many Chevrolet Small Block engines found in trucks from the 1980s and 1990s, provided they use a flat tappet valvetrain. Many trucks from this era came with flat tappet cams, but it's essential to check your specific engine to confirm it's not a factory roller setup.

What is the main performance benefit of this camshaft?

This camshaft provides an improved mid-range power band and better throttle response compared to stock. The 212/212 duration grind is a popular choice for street-driven vehicles looking for a noticeable performance boost without sacrificing too much low-end torque or drivability.

Product Details

This COMP Cams camshaft is designed for Chevrolet Small Block engines, specifically for 350 Tuned Port Injection (TPI) setups that use a performance chip or programmer. It utilizes a hydraulic flat tappet design, meaning it's built to work with that style of lifter and doesn't require special roller valvetrain components unless your specific engine block was factory-equipped for rollers. This camshaft is a popular choice for owners looking to get more out of their classic Chevy V8s.

The CS 260H-12 features a 212 degrees of intake and 212 degrees of exhaust duration at .050 inch lift, with a .447 inch lift on both intake and exhaust. This grind offers a noticeable improvement in throttle response and overall power, especially in the mid-range, without being overly aggressive for street use. It's well-suited for engines in the 262 to 400 cubic inch range, including many popular applications like the 305 and 350 V8s found in a wide variety of GM vehicles from the late 70s through the 90s.

When installing this camshaft, it's important to confirm your engine block's original valvetrain setup. While many later model small blocks (mid-80s and newer) were equipped with provisions for roller camshafts, many trucks and some cars continued to use flat tappet designs well into the 90s. If your block has factory roller provisions and you want to use this flat tappet cam, you'll need to ensure proper lifter compatibility. This camshaft fits a broad range of vehicles, including many Chevrolet C-series trucks, Caprices, and Camaros from the 1980s and early 1990s.
