The Boss engine is a forthcoming all new large-displacement V8 engine project at Ford Motor Company. The engine project was reportedly canceled in 2005 as the company focused on its existing Modular V8 and V10, but was reportedly revived in early 2006 by Mark Fields. [1] The large engine will compete with Chrysler's 6.2 L and larger Hemi engines and General Motors' 7.0 L Vortec engine. The Boss V8 is being built at Romeo Engine in Romeo, Michigan and the first application will be the Lincoln Navigator quickly followed by special edition Ford F-150s.

The 6.2 L Boss engine will reportedly displace 379 cubic inches (6207 cc) and produce roughly 425 hp (317 kW) and 425 lb·ft (576 N·m) upon introduction. The engine architecture will offer the ability to exceed 7.3 L (≈445 cu in) in future applications. Reports indicate the Boss will retain several design similarities with the Modular V8 such as deep skirt block with cross bolted main caps, crankshaft driven gerotor oil pump, and overhead camshaft valve train arrangement. The Boss' single most significant departure from the Modular V8 will be seen in the wider 4.53 in (115 mm) bore centerline; the Modular V8 is 3.94 in (100 mm) by comparison. The 6.2 L will reportedly employ a 4.015 in (102 mm) bore diameter and a 3.74 in (95 mm) stroke to achieve it's 6.2 L of displacement. The initial versions of the Boss will have single overhead camshafts, two valves per cylinder, two spark plugs per cylinder and employ a form of cylinder deactivation for increased fuel economy and reduced emissions.

Initial information on valve sizes of the 6.2 L puts the intake valve at 2.10 in and the exhaust valve at 1.65 in. [2] Later high-performance versions will be equipped with DOHC 4-valve heads and gasoline direct injection (GDI). A "TwinForce" 6.2 L DOHC 4-valve, twin-turbo, GDI version of the Boss is being developed and has reportedly produced over 650 lb·ft (881 N·m) in testing, although there are no known plans time to install this engine in a production application.

Roush Racing is currently field testing an experimental, large displacement version of the Boss engine code named "777" (7.0 L, 700 hp @ 7,000 rpm) at National Mustang Racers Association (NMRA) events around the United States. The 777 Boss is naturally aspirated and runs on e85 biofuel.

The engine was initially called the "Hurricane", but this was changed in mid 2006 to the storied Boss name in the wake of Hurricane Katrina. [3]

2010 Ford F-150 SVT Raptor

In spite of rumors and concerns over the 6.2 L Boss V8's future, Ford has confirmed that the engine will appear in the 2010 F-150 SVT Raptor. Officially unveiled at the 2008 SEMA Show, the SVT Raptor is a high-performance version of the F-150 optimized for off-road use. Though the truck will be initially powered by Ford's 5.4 L Modular V8, the 6.2 L Boss will become available shortly after the truck's launch.[4] Sources covering the SEMA Show have acquired pictures of the SVT Raptor along with the 6.2 L Boss V8 in its engine bay.[5] The SVT Raptor is expected to be launched in the Summer of 2009 with the 6.2 L Boss V8 becoming available by the Winter of 2009.
