SBC Solid Camshaft 545/520

The ISKY Cams SBC Solid Camshaft 545/520 (MPN 201544) is a mechanical flat tappet camshaft engineered specifically for small-block Chevrolet oval track racing engines. This camshaft delivers symmetrical lift of 0.545 inches on both intake and exhaust valves with a 278-degree duration on each valve, optimized for consistent mid-range power delivery and predictable engine behavior in short-track competition environments.

The 108-degree lobe separation angle (LSA) creates a broad torque curve suited to the 2500–6700 RPM operating band typical of oval track applications, where drivers need responsive acceleration off turns without sacrificing top-end power. The mechanical flat tappet design requires proper valve train geometry, lifter preload, and rocker arm geometry for reliability—a consideration critical to any solid camshaft installation. ISKY's manufacturing precision ensures consistent lobe profiles across the shaft, minimizing variation in valve timing between cylinders.

This camshaft is purpose-built for oval track racers running small-block Chevy platforms in classes requiring mechanical valve actuation. The symmetrical intake and exhaust profiles make this shaft equally suited to street performance applications seeking strong mid-range response without the complexity of hydraulic cam followers. Proper installation requires valve train blueprinting, correct pushrod length, and verification of rocker geometry to ensure safe operation and maximum engine lifespan.

Small-block Chevrolet engines with mechanical flat tappet camshafts remain a standard in grassroots racing because of their simplicity, cost-effectiveness, and tunability. ISKY Cams' solid camshafts are widely recognized in oval track circles for repeatability and durability under sustained high-RPM operation, making this shaft a practical choice for competitors balancing performance with reliability.

Each camshaft is supplied as a single unit. Verify your engine's valve train compatibility, pushrod length, and rocker arm specifications before purchase to ensure proper fit and safe operation.
