What is the difference between this camshaft and one with an oiling groove?

This camshaft is a solid flat tappet design without an oiling groove in the rear journal. Certain 1965-1966 396 Big Block engines have this groove, and this specific camshaft will not fit those applications. You would need a different part number for those specific models.

What kind of idle can I expect with this camshaft?

This Xtreme Energy camshaft is designed to produce a noticeable idle. This means you'll hear a distinct sound from the engine that lets you know it's running and performing.

Does this camshaft come with lifters or valve springs?

This product listing is for the camshaft only. You will need to source compatible lifters, valve springs, pushrods, and other valvetrain components separately to complete the installation.

Product Details

COMP Cams is well-known for making performance parts that help engines run better. This Xtreme Energy camshaft is built for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements that originally came with flat tappet camshafts. It's designed to give you improved throttle response and a noticeable idle, making your engine feel more alive.

This camshaft features a 224-degree intake duration and a 230-degree exhaust duration, with a .495 inch intake lift and .525 inch exhaust lift. These specs are chosen to provide excellent response and good mid-range power. It's a solid option for anyone looking to get more out of their Big Block, offering a distinct idle that lets you know the engine is working. Remember, this camshaft is intended for engines originally equipped with flat tappet designs; if your 1965-66 396 has an oiling groove in the rear journal, you'll need a different part.

This camshaft fits a wide range of Chevrolet vehicles from the late 60s through the mid-70s, including popular models like the Chevrolet Impala, Chevelle, and Corvette. It's a great way to wake up the performance of your classic Big Block.
