What type of lifters does this camshaft use?

This COMP Cams CS 252Bh-11 camshaft is designed to be used with hydraulic flat tappet lifters. It is not compatible with factory roller lifter setups without modifications.

Will this camshaft fit my 1990 Chevrolet 350 engine?

It depends on whether your 1990 350 engine came factory-equipped with a roller camshaft or a flat tappet camshaft. Many trucks from that era still used flat tappet cams, but some cars and performance models received roller setups. You may need to remove the intake manifold or timing cover to confirm your engine's original lifter style.

What is the difference between this camshaft and a roller camshaft?

Hydraulic flat tappet camshafts use lifters that slide directly on the cam lobes, requiring specific oiling and break-in procedures. Roller camshafts use roller-tipped lifters that reduce friction and wear, often allowing for more aggressive profiles and better performance, but they require specific blocks and lifter kits.

Product Details

If you're looking to get the most out of your computer-controlled Chevrolet Small Block engine, this COMP Cams CS 252Bh-11 camshaft is a solid option. It's designed to work with hydraulic flat tappet lifters and offers good vacuum and mileage, making it suitable for a wide range of applications from daily drivers to modified street machines. This camshaft fits many Chevy Small Block engines, including popular displacements like the 350 and 400 cubic inch variants, built between 1958 and 2002.

This camshaft features a 201-degree intake and 206-degree exhaust duration at .050 lift, which is a mild profile that balances performance with drivability. This means you'll get improved performance over a stock camshaft without sacrificing too much low-end torque or idle quality. COMP Cams is well-known for producing well-built valvetrain components, and this camshaft is no exception. It’s a popular choice for builders looking for a reliable upgrade that won't break the bank.

When installing this camshaft, remember that it's intended for engines with flat tappet lifters. If your engine was originally equipped with a factory roller camshaft (typically 1985 and newer in many trucks and some cars), this flat tappet camshaft will not be compatible without modifications. Always confirm your engine's lifter style before purchasing. For 1955-1957 Chevy 265 engines, ensure the 5th cam journal has the necessary oiling groove.
