Ford ModularThe 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. [cite web|url=http://www.detnews.com/apps/pbcs.dll/article?AID=/20060326/AUTO01/603260358/1148/AUTO01|title=Hurricane Watch|author=Bryce G. Hoffman|work=Detroit News|accessdate=March 28|accessyear=2006] The large engine will compete with DaimlerChrysler's 6.1 L and larger Hemi engines and General Motors' 6.2 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 Convert|425|hp|kW|0|abbr=on and Auto ftlbf|425 upon introduction. The engine architecture will offer the ability to exceed Auto L|7.0 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.

A "TwinForce" 6.2 L DOHC 4-valve, twin-turbo, GDI version of the Boss is being developed and has reportedly produced over Auto ftlbf|650 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.
