BBC Dowel Knurled Base

The BBC Dowel Knurled Base by DURA-BOND is a precision-engineered component designed specifically for big-block Chevy (BBC) applications. It is essential for ensuring reliable crankshaft alignment and stability between the engine block and cylinder head. This component is particularly useful for those rebuilding classic muscle cars or constructing performance big-block engines.

The knurled base design features precision-machined grooves that create a mechanical lock, enhancing clamp load retention and resisting vibration-induced loosening. This design effectively distributes clamping force evenly across the dowel's contact area, preventing rotation and walkout, which were common issues with earlier smooth-pin designs. Weighing just 0.015 lbs and measuring 3 x 0.5 x 4 inches, this component fits standard BBC block geometry without modification.

Engine builders and restoration shops can rely on the DURA-BOND dowel knurled base for high-horsepower big-block applications. Its design ensures proper alignment and gasket seating, making it an ideal choice for performance and restoration projects. This component is engineered to meet the demands of serious engine builders looking for reliability and precision in their builds.
