The Boss is a forthcoming large-displacement V8 engine project at Ford Motor Company. The engine project was reportedly cancelled in 2005 as the company focused on its existing Triton V8 and V10, but was reportedly[1] revived in early 2006 by Mark Fields. The large engine will compete with DaimlerChrysler's new Hemi and General Motors' large Vortec engines.

The Boss engine will reportedly displace 6.2 L (379 in³, 6208 cc) upon introduction, with the ability to exceed 7.0 L in future applications, and produce more than 425 hp (317 kW) and 425 ft·lbf (576 N·m). It has been rumored that a smaller 5.8 L (355 in³, 5814 cc) version will be developed for a special edition 2009 Ford Mustang and is expected to be the standard V8 engine for the 2010 or 2011 Ford Mustang. The Boss V8s will be built at Cleveland Engine in Cleveland, Ohio. The first application will be Ford's F-Series pickup trucks produced at Dearborn Truck. It has been rumored that the Boss will retain many of the Modular V8 design cues such as a deep skirt block with cross bolted main caps, oiling system design, and overhead camshaft valve train arrangement. The Boss' single most significant departure from the Modular V8 will be the significantly wider 4.53 in (115 mm) bore centerline. It has been rumored that the 6.2 L will employ a 4.015 in (102 mm) bore diameter and a 3.74 in (95 mm) stroke to achieve it's displacement while the 5.8 L version will retain the 6.2 L's bore diameter but employ a shorter 3.503 in (89 mm) stroke. The initial versions of the Boss will have two-valves-per-cylinder, two spark-plugs per cylinder and likely employ a form of cylinder or valve deactivation for increased fuel economy. Later high-performance versions will be equipped with DOHC, four-valves-per-cylinder and Gasoline direct injection (GDI). There are rumors of a 6.2 L, DOHC, four-valves-per-cylinder, twin-turbo, GDI version of the Boss already under development.

Initial information on valve size, puts the intake valve at 2.10" and 1.65" exhaust [2]

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

5.8l Engine Rumor In 09 (355)

[raceruler03]

that would be sweet

[BWAL]

ford needs a 7.0, but ford also needs a platform to put it to good use in, maybe build something to compete with the c6 z06

[Drgnracin72]

they need to do something, becasue the 4,6 isnt cutting it.

What they nmeed to do is use the mustang platform, but use lightweight parts, to get the weight around 3200 lbs, ditch the front strut suspension, and stick an IRS in it, the put a blown all aluminum 351 in it or an n/a 427 so ford can finally say to the ZO6 and Viper.

I guess No one Cares about a

6.2L DOHC 32v Twin Turbo Boss Mustang.

[TheUNZippee!]

I would love to see Ford come out with a 5.0 or 5.8L motor with DOHC, and drop the cars weight to 3,200lbs but I dont see the weight part happening because safety standards keep getting bumped up

[03 R Code]

They need to do all that weight saving on a new Ford GT platform and put the monster motors in that. If the mustang came with it it wouldn't be practicle for the majority of people to buy, they would stop selling so many cars and it would eventually end up like the 'maro and bird did. Possibly without ever coming back. The mustangs don't need to try to compete with a vette, they should leave that to the ocassional GT and the mustang for the maros and birds.

I'd still be thrilled if there were a big block option in any new mustang!

[evilcow]

With rumors of the Camaros having 450HP for SS versions I think it is very likely Ford will come out with an engine to compete. With gas prices only going up I would expect this engine to only be in special Boss or Cobra edition Mustangs and not the standard V8. The standard V8 will most likely be a 4.6L or 5.0L with direct injection making about 350HP and getting the same or better gas milage as the 08s. The Mustang has always been a mass appeal car. I don't think a lot of people will want a 6.2L engine.
