What is the recommended stall speed for this camshaft?

This COMP Cams Xtreme Energy camshaft is designed for use with a torque converter that has a stall speed of 2800 RPM or higher. This helps ensure the engine stays in its power band during acceleration.

Does this camshaft come with lifters or other valvetrain components?

This product is for the camshaft only. You will need to source compatible hydraulic flat tappet lifters, valve springs, retainers, and pushrods separately to complete the installation.

How can I tell if my engine is compatible with a flat tappet camshaft?

You'll need to remove the intake manifold or timing cover to inspect the camshaft and lifters. If the lifters are roller-tipped and ride on a roller on the camshaft, it's a roller setup. If the lifters are flat on the bottom and ride on a flat lobe, it's a flat tappet setup.

Product Details

Starting with a camshaft duration of 240 degrees on the intake and 246 degrees on the exhaust, this COMP Cams Xtreme Energy camshaft is built for Chevrolet Small Block engines that need more grunt. This hydraulic flat tappet cam is designed to bridge the gap between a mild street cam and a full-on race piece, giving you a noticeable bump in torque and throttle response without making the valve train overly noisy. It’s a solid option for those looking to improve their engine’s performance for street/strip applications, especially when paired with headers and appropriate gearing.

This camshaft is well-built to handle the demands of daily driving while still offering the performance gains you're looking for. It’s engineered to work with a 2800+ RPM stall torque converter and is known to produce a rougher idle, which is typical for cams of this performance level. You can expect increased vacuum and power output compared to stock, making your engine feel more responsive. Remember that this camshaft is intended for engines with flat tappet configurations, so it's important to verify your block's setup before installation, as many later model Small Blocks switched to factory roller setups.

This camshaft fits a wide range of Chevrolet Small Block engines, including popular displacements like the 350, 400, and 327, found in vehicles such as the Chevrolet C10, Camaro, and Caprice. It’s important to note that this camshaft is not compatible with LT1/LT4 engines or factory roller small blocks from 1985 and newer, and it does not fit LS-based engines. For optimal performance, consider pairing this camshaft with headers and a higher stall speed torque converter.
