How do I know if my Chevrolet Small Block has a flat tappet or roller camshaft?

You'll need to inspect the camshaft itself. Generally, factory roller camshafts were introduced around 1985 and became more common through the 1990s, especially in trucks and SUVs. Removing the intake manifold or timing cover is often necessary to confirm whether your engine has a flat tappet or roller setup.

What is included in the COMP Cams CL12-206-2 kit?

This kit comes with the CS 260H camshaft, a set of hydraulic lifters, assembly lube to help with installation, COMP Cams decals, and detailed installation instructions.

Will this camshaft fit my 1990 Chevrolet 350 engine?

It depends on whether your 1990 350 engine is a factory roller or flat tappet. While many trucks and SUVs from that era still used flat tappet cams, GM gradually transitioned. You should confirm your engine's camshaft type before purchasing, as this kit is specifically for flat tappet applications.

Product Details

This is the COMP Cams CS 260H hydraulic flat tappet camshaft and lifter kit, designed for Chevrolet Small Block engines. It's a popular choice for applications like vans, pickups, 4WD vehicles, and towing setups where you need strong mid-range torque and a good idle, especially with 350 cubic inch engines. It's also suitable for single or dual engine setups in marine applications for ski boats and economy cruising.

This kit includes the camshaft, lifters, assembly lube, decals, and instructions, making it a complete package for your engine rebuild. The CS 260H profile is known for providing a noticeable improvement in the mid-range power band, which is crucial for getting heavier vehicles moving or maintaining speed under load. It's a well-built kit that offers a solid upgrade over stock camshafts for these specific engine types.

It's important to note that this kit is for flat tappet camshafts and does not fit factory roller Small Blocks from 1985 and newer, or LT1/LT4 engines. You may need to remove the intake or timing cover to confirm your block's configuration, as GM transitioned to roller cams gradually. Early 1955-1957 Chevrolet 265 engines also have a specific oiling requirement on the 5th cam journal.
