Ford Performance BOSS 351 Engine Block; 9.20-Inch Deck

Performance Engine Block Upgrade. The Ford Performance BOSS 351 Engine Block is designed primarily for performance. If you want to take your Mustang from the streets to the track, this is one of the early upgrades you should consider. This is a great upgrade from stock, as it is constructed using the latest technology and manufacturing techniques from both the production and racing worlds.

Quality Materials and Construction. The Ford Performance BOSS 351 Engine Block underwent the cast iron construction in order to get the strength and durability needed for racing applications. It is cast from diesel-grade iron and designed with added material in key areas to create an engine block far superior to any Ford OE block ever produced. It has a 9.20-inch deck height, finished at 9.200 inches plus 0.010 to 0.015 inches, and a 4.125-inch bore capacity, finished at 3.990 to 3.995 inches rough bore.

Direct-Fit Installation. This Ford Performance BOSS 351 Engine Block is a direct-fit replacement for the BOSS 351 block. It is designed to directly install on where the original block once was with minimal adjustments. It has revised oiling and cooling system passageways but is still compatible with the original 351W blocks. It is meant to accept factory roller lifter guides and lifter guide retainer for easy installation.

No Warranty Included. Most Ford Racing Performance parts, including this BOSS 351 Engine Block, are sold with no warranty. They are sold “as is,” “with all faults,” “as they stand,” and without any express warranty whatsoever, unless otherwise expressly designated. Should the part be defective following the purchase, the buyer and not the manufacturer, distributor, or retailer, shall assume the entire cost of servicing or repair.

Application. This Ford Performance BOSS 351 Engine Block is designed to fit all Ford Mustang models.
