The Comp Cams SBC Cam CS-300B-6 is a mechanical flat tappet camshaft engineered for small block Chevy engines seeking a balance between street manners and high-RPM capability. This solid-lifter cam delivers 0.562-inch intake and 0.557-inch exhaust lift across a 300/314-degree duration profile, making it ideal for engines built to operate reliably from 3500 to 7200 RPM with a 106-degree lobe separation angle.
The specifications on this small block Chevy camshaft translate to controlled valve events that maintain street-friendly idle characteristics while supporting aggressive power production in the mid to upper rpm range. The 106 LSA (lobe separation angle) positions the intake and exhaust events to optimize scavenging without excessive overlap, a critical consideration for engine builders tuning carburetor or EFI induction systems. Mechanical flat tappet design requires proper valve train geometry and rocker arm ratios to function safely; users must verify compatibility with existing components before installation and ensure correct break-in procedures are followed to prevent accelerated wear.
This profile suits small block builders targeting muscular street performance, weekend track use, or bracket racing applications where moderate lift and mid-range duration deliver usable torque without sacrificing low-rpm drivability. Buyers investing in a new camshaft should pair it with complementary components—including a quality fuel pump, ignition system rated for the intended RPM range, and a valvetrain capable of maintaining preload—to realize the intended performance envelope. Comp Cams' reputation in the performance engine market reflects decades of cam design and testing across thousands of small block applications.
