Ford Boss 429 Engine Buildup - The Boss

Perception and reality are often widely disparate things. That couldn't be truer than with the legendary Boss 429 Mustang and the semi-hemi engine for which it was named.Perception and reality are often widely disparate things. That couldn't be truer than with the legendary Boss 429 Mustang and the semi-hemi engine for which it was named. It is the darling of the Mustang collector world, and the mere mention of its name conjures images of asphalt-annihilating stop-light exhibitions.inline_mediumwraptextright00The new Boss '9 build began with a Ford Racing 460 cylinder block, PN M-6010-A460. It's an updated version of the original 385-series block that spawned the original Boss 429, although the original block had four-bolt mains and a denser iron composition when compared with the standard 429/460 design. The block is designed for competition use, so it's stronger than the original blocks, too, and comes with four-bolt mains. A 10.320-inch deck height is standard on the new block and matches the production spec of the original Boss 429 engine. This engine, however, was machined for 4.375-inch bores, which are 0.015 inch larger than the original engine. This delivers a 432ci displacement, but the block can support a displacement of up to 598 inches.29148997/techarticles/engine/hrdp_1006_ford_boss_429_engine_builduphrdp_1006_02 _o+ford_boss_429_engine_buildup+bare_block.jpgtrue
