M-6010-B35192BB – Ford Performance Parts

BOSS 351 ENGINE BLOCK 9.2 DECK BIG BORE

In the world of racing and performance, BIGGER is always better. Ford Performance gets it – and that’s why it offers BOSS small blocks in Big Bore versions. The Ford Performance BOSS blocks are designed to be a replacement for the legendary BOSS 302 and BOSS 351 blocks using the latest technology and manufacturing techniques available. Cast from diesel grade iron with siamese bores, thick cylinder walls and decks, BOSS block strength is far superior to any Ford production block ever offered.

Ford Performance Big Bore 351 blocks make it simpler and more economical to build really BIG small blocks. To insure the most precise bore location, concentricity and integrity, the BOSS Big Bore blocks are machined an additional .125″ during the initial block fixturing and boring stage. With an unfinished bore size of 4.120″, Ford Performance BOSS 351 Big Bore blocks make really BIG small blocks.

The Ford Performance BOSS block capability has been proven around the world, both on the track and on the street. And, all Ford Performance BOSS blocks are cast and machined to the highest industry standards in the USA.
