What is the correct break-in procedure for this camshaft?

Solid flat tappet camshafts require a specific break-in procedure to prevent premature wear. This typically involves using a break-in oil additive and running the engine at approximately 2000-2500 RPM for 20-30 minutes immediately after installation. Always refer to the manufacturer's detailed instructions for the exact procedure.

Does this camshaft come with lifters or other installation hardware?

This part number is for the camshaft only. Lifters, valve springs, pushrods, and other necessary valvetrain components are sold separately and should be chosen to match the camshaft's specifications for optimal performance and durability.

Can this camshaft be used in a 1966 Chevrolet Big Block engine?

No, this specific camshaft (11-106-3) is not compatible with 1965-1966 Big Block engines that have an oiling groove in the rear journal. For those specific applications, you will need to contact COMP Cams directly to order the correct camshaft with the oiling groove.

Product Details

This is the COMP Cams CB Replacement Camshaft, part number 11-106-3, designed for Chevrolet Big Block 396 to 454 cubic inch engines originally equipped with flat tappet camshafts. If you're looking to restore or enhance the performance of a classic muscle car like a 1967-1973 Chevrolet Chevelle, a 1967-1974 Corvette, or a 1967-1976 Chevrolet Impala, this camshaft is built to meet those needs.

This camshaft features a 242 degrees intake and 242 degrees exhaust duration at .050 lift, with a .525 lift on both intake and exhaust. It's a solid flat tappet design, intended to replicate the performance characteristics of factory muscle car engines from the late 60s and early 70s. The camshaft is well-built with durable materials to ensure it holds up under the demands of a performance engine. It's important to note that this specific camshaft is not compatible with 1965-1966 Big Block engines that have an oiling groove in the rear journal; for those applications, a different part number is required.

When installing this camshaft, ensure you follow proper break-in procedures for solid flat tappet camshafts, which typically involves using a specific break-in oil and running the engine at higher RPMs for a set period. This helps to properly seat the lifters and prevent premature wear.
