COMP Cams Camshaft CS Xt250H-10

If you're building a single turbo street machine for your classic Chevy small block, this COMP Cams camshaft is a solid option. It’s designed for applications running 5 to 10 pounds of boost, giving you an improved powerband for street use without needing excessive boost pressure. This camshaft works with hydraulic flat tappet lifters, making it a straightforward upgrade for many older Chevy V8s.

This camshaft features a 206-degree intake and 206-degree exhaust duration at .050 inch lift, which is a popular choice for street-driven turbo builds. This duration provides a good balance between idle quality and top-end power, helping your engine breathe better under boost. It's built for Chevrolet Gen 1 Small Blocks ranging from 262 to 400 cubic inches, fitting a wide variety of popular engines like the 350, 305, and 400 small blocks.

Keep in mind that this camshaft is intended for engines with flat tappet lifters. If your engine was built from 1985 or later and has provisions for roller lifters, you'll need to confirm whether your block currently uses flat tappet or roller lifters before installation. For engines from 1955-1957, ensure your 5th cam journal has the necessary oiling groove.
