Ford introduces all-new Boss 351 high-performance engine block

Article by Christian Andrei, on August 27, 2010

Although it was used beginning the early part of the 60s, the Windsor 351 small-block V8 powerplant by Ford has not totally faded from the scene since the carmaker has come up with a new performance powerplant based on the design of the original unit. =

The new powerplant, which is intended for both racecars and high performance street vehicles, is dubbed the Boss 351 and can manage displacements ranging from 351 cu. in. (5.7 liters) up to 460 cu. in. (7.5 liters).

The latest tooling and a host of technological upgrade went into the creation of the new engine block, which consists of splayed main bolts and double bores with engineered coolant cross-drilling.

A non-cross-drilled variant of the block with a higher bore capacity will be offered in the third quarter of the year.

The engine block is created from diesel-grade iron with a tensile toughness of 41k psi and it comes with a Cleveland-sized 2.75 inch main bearing journal. The maximum bore of the block is 4.125 inches and a 4.25 inch stroke limit, contingent on the crankshaft employed. 

There are two different deck heights being offered: 9.2 inches and 9.5 inches, with four-bolt main caps and screw-in plugs.

By the fourth quarter of the year, a complete crate engine that is based on the 351 with 427 cu. in (7.0 liter) displacement will be also offered. The current engine block is available with a price tag of $1,999.
