the April 2010 issue of Circle Track Magazine, the editors built a Late
Model Stock engine using the BOSS 351 block. To check out the article, visit the Circle Track site here.

In the world of racing and performance, BIGGER is always better. Ford Racing gets it - and thats why it offers BOSS small blocks in Big Bore versions. The Ford Racing 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 Racing 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 Racing BOSS 351 Big Bore blocks make really BIG small blocks - as big as 460 cubic inches!

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