What is the difference between this camshaft and one for early 396 engines?

Early 1965-1966 396 Big Block engines have an oiling groove in the rear journal that requires a specific camshaft. This CB 260AH-12 camshaft does not have provisions for that oiling groove and is not compatible with those specific early models.

What kind of performance improvements can I expect with this camshaft?

This camshaft offers an updated profile with 212 degrees of intake and 218 degrees of exhaust duration. It's designed to improve your engine's breathing and power output, providing a noticeable enhancement over stock camshafts for street-driven applications.

Does this camshaft come with lifters or other installation hardware?

This product listing is for the camshaft only. Lifters, valve springs, pushrods, and other necessary installation hardware are sold separately and should be checked for compatibility with your specific engine build.

The camshaft features a 212 degrees of intake duration and 218 degrees of exhaust duration, with a lift of .462 inches on the intake and .480 inches on the exhaust. This profile is well-suited for a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including models like the Chevrolet Impala, Camaro, and C10 Pickup. It's a solid option for those looking to enhance their engine's breathing and power output without going to an extreme setup.

Please note that this camshaft is not CARB approved and cannot be shipped to California. Also, be aware that 1965-1966 396 Big Block engines with an oiling groove in the rear journal require a specific camshaft; this part number is not compatible with those particular early models.
