Why start your engine build with a worn-out production block from decades ago that needs hours of machine work. When you can start with a new heavy-duty cast iron engine block that is a semi-finished bare engine block that requires very little machining to match your internal components. These brand-new aftermarket engine blocks are cast from premium high-strength Class 32B iron. It features Siamese cylinder bores and splayed billet steel four-bolt main caps with priority main oiling system which direct oil straight to the main bearings. The extra thick standard deck height ensures a reliable head gasket seal as well as allowing the use of off the shelf standard components such as camshaft, timing chain, oil pump/pan and oil filter etc.
