Choose from 371, 427 or 460 cubic inches for your Ford. Add a set of cylinder heads, your intake, exhaust, ignition and lubrication system and you’re in business! Rotating assemblies are precision-balanced. You’ll get a complete, pro-built short block (featuring the incredible new World MAN O’ WAR 302/351 replacement block) with all the right stuff for a price that’s probably less than you can round up the parts alone for.

Want to build it yourself? Get a kit that comes with a fully race-prepped block and a balanced rotating assembly and you'll be able to put it together in the comfort of your own shop!
