What vehicles does this camshaft fit?

This camshaft is designed for Chevrolet Gen 1 Small Block engines, covering many displacements from 262 to 400 cubic inches. It fits a broad range of vehicles from the 1980s and early 1990s, but it's crucial to verify your engine has a flat tappet valvetrain and is not a factory roller from 1985 or later.

What modifications are recommended with this camshaft?

For best results, COMP Cams recommends pairing this camshaft with improved intake manifolds, cylinder heads, headers, and a suitable carburetor. These supporting modifications help the engine take full advantage of the camshaft's improved airflow and performance characteristics.

Does this camshaft fit my 1986 Chevrolet 350 engine?

While this camshaft fits many Chevrolet 350 engines, 1985 and newer models may have come factory-equipped with roller camshafts. It's recommended to remove the intake or timing cover to confirm whether your specific 1986 engine uses a flat tappet or a factory roller valvetrain before purchasing.
