What type of distributor gear is required for this camshaft?

This COMP Cams 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.

Does this camshaft fit my 1988 Chevrolet 350 engine?

Yes, this camshaft fits Chevrolet GEN 1 Small Blocks including the 350 engine from 1988. However, it does not fit factory roller small blocks from 1985 and newer, so you will need to confirm if your specific 350 has a flat tappet or factory roller setup.

What other engine modifications are recommended for this camshaft?

This camshaft is designed for high-performance drag racing builds. It is recommended for engines with 350-400 cubic inches, a 5000+ RPM stall converter, 11.5:1 or higher compression, and ported cylinder heads to achieve optimal performance.

Product Details

COMP Cams is well-known for performance engine components, and their camshafts are a popular choice for builders looking to get more out of their engines. This CS 313R-6 solid roller camshaft is specifically designed for drag racing applications on Chevrolet Small Block engines, targeting builds with 350-400 cubic inches, a 5000+ RPM stall converter, 11.5:1 or higher compression, and ported cylinder heads.

This camshaft features a 276-degree intake duration and 284-degree exhaust duration with a .050 inch lift duration of 230 degrees on the intake and 236 degrees on the exhaust. It has a lobe separation angle of 110 degrees and lift figures of .600 inches on the intake and .600 inches on the exhaust. It's optimized for use with a Melanized or Nitrided distributor gear to ensure proper operation and longevity; using cast or steel gears without these surface treatments will void the warranty. This camshaft fits a wide range of Chevrolet GEN 1 Small Blocks, including popular displacements like the 305, 327, 350, and 400, but it does not fit LT1/LT4 engines or factory roller small blocks from 1985 and newer. It also excludes LS-based engines. For 1955-1957 models, confirm if your block requires an oiling groove on the rear journal.

When installing this camshaft, it's crucial to use the correct distributor gear as specified. This part is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting modifications, such as a high-stall torque converter and appropriate compression ratio, to take full advantage of this camshaft's performance potential.
