HOWARDS RACING COMPONENTS 114393-14S Howards Racing Components 114393-14S SBC Big Bottle Mechanical Roller Camshaft

The Howards Racing Components 114393-14S Big Bottle camshaft is designed for Small Block Chevrolet engines requiring a high-performance mechanical roller profile. This camshaft features a 4/7 firing-order swap configuration, helping support performance engine combinations built around revised firing-order requirements. It is supplied as an individual camshaft and is intended for applications operating within a demanding high-RPM range.
The camshaft delivers 0.675-inch lift at both the intake and exhaust valves, with advertised durations of 309 degrees on the intake side and 323 degrees on the exhaust side. Its 114-degree lobe separation angle is engineered to define the valve-event relationship and powerband characteristics of the profile. The 5,000 to 9,000 RPM operating range makes this camshaft suitable for serious racing and competition-focused Small Block Chevy builds where upper-RPM performance is a primary consideration.
As part of the Howards Racing Components Big Bottle Cam series, the 114393-14S combines a mechanical roller design with an aggressive valve-train profile for builders seeking increased airflow potential and high-speed performance. Proper valve-train components, installation procedures, lash adjustment, and supporting engine modifications should be selected to match the camshaft specifications and intended application. Verify engine compatibility, cylinder-head clearance, compression ratio, induction system, and complete valve-train requirements before installation.
