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 will void all warranties and return policies.

What other upgrades are recommended for maximum performance with this camshaft?

For the best results, it is recommended to upgrade your intake and exhaust systems. Additionally, a torque converter with a 2500+ stall speed is suggested to take full advantage of the camshaft's performance capabilities.

How can I tell if my engine block is compatible with this roller camshaft?

You will need to remove the intake or timing cover to inspect your block. Look for provisions for roller lifters. While many '87+ GM engines received roller provisions, some trucks and SUVs from the mid-80s to mid-90s may have had flat tappet cams installed. COMP Cams offers specific kits for retro-fitting roller components if your block has the provisions.

Product Details

This is the COMP Cams CS 280XFI HR-13 camshaft, a hydraulic roller camshaft designed for a significant performance increase in Chevrolet Gen 1 Small Block engines. It's specifically tuned for EFI applications, meaning it works well without needing the extra airflow signal typically found in carburetor setups. This camshaft is a great choice for a "hot street" build, aiming to give your engine more power and responsiveness.

The XFI (Xtreme Fuel Injection) designation means it uses COMP Cams' newest and quickest lobe profiles, which are optimized for fuel-injected engines. This camshaft features wider lobe separation, which helps maintain responsiveness even with the improved airflow. For maximum performance gains, it's recommended to upgrade your intake and exhaust systems, and it pairs well with a torque converter with a 2500+ stall speed. COMP Cams also notes that this camshaft is optimized for use with a Melanized or Nitrided distributor gear, and using cast or steel gears without similar surface treatments will void the warranty.

This camshaft fits a wide range of Chevrolet Small Block engines from 1958 through 2002, including popular applications like the 350, 327, and 400 cubic inch V8s found in vehicles such as the Chevrolet C10, Camaro, and Caprice. It's important to verify your specific engine block's provisions for roller lifters, as some later model trucks and SUVs may have had flat tappet cams even in roller-capable blocks. If your block has provisions but lacks roller components, COMP offers specific hydraulic roller lifter kits for '87+ blocks.
