SBC Billet Front Main Cap

The SBC Billet Front Main Cap from Howards Racing Components is designed for small-block Chevrolet engines that require precision-machined internal components exceeding OEM durability standards. This component is essential for both street performance and race applications, providing a critical bearing surface that supports the crankshaft under high loads and sustained RPM.

Constructed from premium billet aluminum, the H350F cap eliminates the porosity and inconsistencies found in cast iron OEM components, resulting in superior concentricity and bearing alignment. The billet construction allows for tighter tolerances and improved oil flow characteristics, which are crucial when using high-performance gaskets and upgraded main bearing sets.

This front main cap is compatible with small-block Chevrolet 350 engines and must be properly torqued to specification and honed to ensure correct bearing clearances during final assembly. It integrates seamlessly into complete engine builds, stroker conversions, and high-displacement variants, maximizing internal structural integrity for enhanced engine longevity and power delivery.
