Oil Pump Shaft BBC for 1.00 IN. Raised Cam

The Oil Pump Shaft BBC for 1.00 IN. Raised Cam is a precision-engineered drive component designed for big block Chevy engines running raised camshaft profiles. This component serves as the critical link between your oil pump and camshaft, transferring rotational force to ensure proper lubrication at elevated valve timing configurations. Whether you're building a street performance engine, a race-ready big block, or upgrading an existing BBC platform, this pinned steel shaft accommodates the specific geometry demands of 1.000-inch raised cam installations.

Manufactured by MOROSO, a trusted name in engine performance components, this oil pump drive shaft is constructed from durable steel and features a pinned sleeve design that locks the shaft securely to both the oil pump and camshaft drive gear. The 7.5-inch length is specifically engineered to work with big block Chevy platforms using raised camshaft configurations, ensuring proper alignment and clearance within tight engine compartments. The pinned design eliminates slippage under load, maintaining consistent oil pump engagement regardless of RPM or boost conditions, which is critical for maintaining oil pressure stability during high-performance operation.

Performance builders and mechanics upgrading to raised cam profiles rely on this shaft to maintain reliable oil delivery without requiring extensive engine bay modifications. Installation requires removal of the timing cover and old pump drive components, making it ideal for engine rebuilds, cam swaps, or complete powerplant restorations. Proper fitment is essential—the 1.000-inch raised cam specification ensures compatibility with your specific big block Chevy configuration, preventing installation errors that could compromise oil flow and engine longevity.
