Sbc Cam&Lifter Kit 306s (Solid Lifter #813-16)

The COMP Cams SBC Cam & Lifter Kit 306S with Solid Lifter #813-16 is a complete mechanical flat tappet camshaft and lifter assembly engineered for small block Chevy engines seeking moderate lift and duration in the 3,000–7,000 RPM band. This kit combines a precision-ground camshaft with matching solid lifters, eliminating the need for separate sourcing and ensuring proper valve train compatibility from the outset.

The 306-degree duration on both intake and exhaust, paired with 0.555-inch lift per side, delivers a balanced power curve suited to street and mild performance applications. The 110-degree lobe separation angle (LSA) is a well-established specification for naturally aspirated small block engines, providing smooth idle quality while maintaining responsive mid-range torque. Solid lifter designs eliminate hydraulic lag and are preferred in serious performance builds where tight valve train geometry and consistent actuation matter. COMP Cams' manufacturing standards ensure repeatable lobe profiles and proper surface finish to minimize wear on cam lobes and lifter faces during break-in and extended use.

This kit addresses builders and engine enthusiasts restoring or upgrading small block Chevy platforms—from classic muscle cars to hot rods and street performance engines. The complete kit format streamlines assembly by eliminating fitment guesswork and ensuring the camshaft and lifters are matched for optimal durability. Builders appreciate COMP Cams' reputation for quality casting, precision grinding, and consistency across production runs, reducing variables in valve train setup and tuning.

Within the small block Chevy ecosystem, a 306-degree solid lifter cam represents a middle ground between stock and aggressive performance profiles. It suits engines with moderate compression ratios and standard cylinder head flow, making it a sensible choice for builders seeking reliable power without the complexity of high-lift, long-duration grind or the ongoing maintenance of adjustable rocker systems.

Part number CL12-225-4 is COMP Cams' standard designation for this specification. The kit weighs 12.75 lbs and ships in compact dimensions, making storage and transport straightforward for engine builders and machine shops.
