Performance Engine Block. The Ford Performance BOSS 351 Big Bore Engine Block is designed primarily for racing and performance. This is a quality replacement for the BOSS 351 block using the latest technology and manufacturing techniques. This is to create an engine block that will really push your muscle car to the limit.

Quality Construction. This Ford Performance BOSS 351 Big Bore Engine Block is cast from diesel-grade iron with Siamese bores and thick cylinder walls and decks.

Moreover, it has a 4.185-inch bore capacity, finished at the 4.12-inch rough bore.

Direct-Fit Installation. The Ford Performance BOSS 351 Big Bore Engine Block is designed as a replacement for the BOSS 351 block, so it directly installs to where the original block once was. It is designed to be compatible with the original 351W blocks. It is also machined to accept factory roller lifter guides and lifter guide retainer for a relatively easier installation.
