World’s unique MAN O’WAR aluminum block represents the state of the art design in small block Ford technology, incorporating many important features that leading Ford racers have asked for. Tipping the scales at only 90 lbs. the MAN O’WAR is reinforced throughout, and has provisions for two extra head bolts per cylinder to provide superior clamping of the heads, essential for high combustion pressure applications. World’s MAN O’WAR 10° cylinder heads are similarly equipped to be the perfect match to the block. Add 1045 billet steel splayed 4-bolt mains and ARP hardware for bottom end strength and bring on the power adders!

There are many important reasons why World’s MAN O’WAR aluminum blocks are the most reliable of their kind on the market. It features a priority main oiling system which ensures that the crankshaft is lubricated first and the cylinder heads last. Water jackets are expanded over other block designs to improve cooling. And the block is reinforced in all critical areas, including bulkheads, mains, and valleys. It’s a CAD engineered masterpiece!
