Description: If your looking for strength and mechanical reliability, Olds Performance Products offers an alternative to the weak factory cast iron caps. Made from the finest grade of material, these caps will endure the loads of engines that produce higher hp levels from increased compression, higher rpms and larger cubic inches. Each main cap goes through the extensive process of EDM which allows for tolerences to be held within .00005. This process ensures a perfect fit to the factory engine block surfaces. Shown here for 400,425 and 455 engine blocks. Sold in sets of four with black Oxide coating.
