BBC Magnum 3/8in Pushrods 8.28in Int./9.2

The BBC Magnum 3/8in Pushrods 8.28in Int./9.2 by COMP CAMS are purpose-built valve train components designed for serious marine engine builders and performance boaters who demand reliability under high RPM conditions. These pushrods are engineered to handle the demands of big-block Chevy applications, where precise valve actuation translates directly to engine efficiency and dependability on the water. Whether you're rebuilding a classic displacement engine or upgrading an existing platform, these pushrods represent the engineering standard that professional technicians trust in high-performance marine powerplants.

COMP CAMS pushrods deliver consistent valve timing through a rigid, precision-manufactured design that minimizes deflection and harmonics at elevated engine speeds. The 3/8-inch diameter profile provides optimal strength-to-weight ratio, while the 8.28-inch internal measurement with 9.2-inch overall length ensures proper geometry for BBC (big-block Chevy) head and block configurations. The hardened steel construction resists wear and fatigue, critical factors when cam profiles push higher valve lift and aggressive lobe separation angles common in marine racing and high-output applications.

These pushrods suit builders upgrading from stock components to aftermarket cam packages, or those restoring engines to original specifications with attention to quality. Installation requires proper pushrod length measurement for your specific head and block combination to ensure correct preload and rocker arm geometry. Compatibility is confirmed by verifying your engine's BBC designation and checking that adjuster and rocker arm cup dimensions accommodate the 3/8-inch diameter. For boaters running marine-grade BBC engines—whether naturally aspirated or boosted—COMP CAMS pushrods provide the valve train control needed for sustained power and longevity.
