Block Engineering Details and Features
Oil Pressure System
The new Block is cast and machined from modern high strength cast iron. All interface surfaces for any standard attached parts match the original block design so that original or new aftermarket parts can be used in the build process. The new block features larger streamlined intake ports and an internal closed pressurized oil lubrication system that feeds oil directly to the main journals, rear main trust bearing, and camshaft bearing journals. The Block has replaceable cam bearings fitted for use with either a 3 or 5 bearing camshaft and hard exhaust valve seats. The rear crankshaft seal is a common radial lip seal.
