What type of distributor gear is required for this camshaft?

This camshaft is optimized for use with a Melanized or Nitrided distributor gear. Using cast or steel gears without similar surface treatments is not compatible and will void the warranty.

Can this camshaft be used in an engine with factory roller lifters?

This camshaft is designed for engines that are either flat tappet or have provisions for roller lifters. If your '87+ block has roller provisions but no components, a COMP Hydraulic Roller Lifter Install Kit can be used. It is not compatible with LT1/LT4 or factory roller Small Blocks built from 1985 and newer.

What other components are recommended for this camshaft setup?

For optimal performance, this camshaft is recommended for use with nitrous systems of 175 horsepower or more, a torque converter rated at 2500 RPM or higher, lower rear-end gears, and headers. Always refer to manufacturer guidelines for complete build recommendations.

Product Details

This COMP Cams Nitrous HP camshaft is designed for Chevrolet Small Block V8 engines, specifically those from 1958 through 2002 with displacements ranging from 262 to 400 cubic inches. It's built to work with nitrous systems of 175 horsepower or more, and pairs well with a torque converter rated at 2500 RPM or higher, especially when combined with lower rear-end gears and headers. This camshaft features wider lobe separation and increased exhaust duration compared to the base XE series, which helps to move the powerband higher in the RPM range, making it ideal for nitrous applications. The early exhaust opening is a notable design choice that aids in scavenging the extra exhaust gases produced by nitrous or forced induction, contributing to better performance at the drag strip.

The Nitrous HP camshaft utilizes a hydraulic roller design, which offers reduced friction and improved performance over flat tappet systems. For optimal performance and to maintain warranty, it's crucial to use a Melanized or Nitrided distributor gear; cast or steel gears without similar surface treatments are not compatible. If your engine is an '87 or newer Small Block with provisions for a roller camshaft but lacks the factory roller components, COMP offers a Hydraulic Roller Lifter Install Kit and an OE-style Hydraulic Roller Cam specifically for these blocks.

This camshaft is a solid option for a range of classic Chevrolet and GM vehicles, including models like the Chevrolet Caprice, Buick Roadmaster, and AM General Hummer from the specified years. It's important to verify your engine's configuration, as GM gradually introduced roller camshafts from the mid-80s onward, with trucks often retaining flat tappet cams until the mid-90s. Always consult the manufacturer's installation instructions for specific details regarding distributor gear compatibility and any other requirements for a successful build.
