World Products "MOW" Blocks

****ALL BLOCKS COME WITH BILLET CAPS NOW****

From all measurable standards, World Products’ trendsetting MAN O’WAR cast iron block is the ultimate iron SBF block

It comes in various deck heights to match the application. You should know that the MAN O’WAR block was used to win the Engine Masters Challenge, and that its design allows huge displacements. Add provisions for 2 extra bolts per cylinder and you can see why it’s a favorite of serious Blue Oval racers! 

The MAN O’WAR block was designed from scratch (in collaboration with a leading NASCAR team) using CAD/CAM and 3D design technology. With the ability to design not only the part but the tooling to manufacture it, World’s engineering team has come up with an elegant design that can be cast and machined to exacting specs. Like all other World blocks, the MAN O’WAR is machined using only two fixturing operations, avoiding the tolerance stacking found in OEM production lines.
