i just read in wheels that ford is ditching the mighty BOSS v8 and going back to pushrods of 5.8l and 6.2l WHY GO BACKWARDS might aswell put square wheels on them to

Pushrod engines are cheaper to build. With the latest in port design and cam technology, why not?

I'm quite sure wheels is wrong. They just stuffed it up. The new Hurricane/Boss engine is reported to be single OHC with capicity from 5.8 to 7.0 litre and the later perf models will be quad cam 4valve/cyl.

check this link but remember this is not official Ford release Ford Boss engine - Wikipedia, the free encyclopedia

what we have heard over here is that the motor can be used with or without pushrods. in other words, it has a lifter galley, and is designed for OHC. it allows different engine dimensions for different vehicle compartments.




maybe it's garbage, but it's what is out there.

All reports indicate the new engine family will NOT be pushrod. It will be an overhead cam design, but not related to the modular family.

who cares whether its pushrod or OHC, as long as the important characteristics are all there, ie - power, economy, and a decent/usuable rev range. The last point is where the current Ford V8's apparently fall short.

Fer Chrissakes Give Us Another 600 Rpm To Play With No Matter What The Configuration!!!

I heard a rumour that the new engine from 2010 would be the Jaguar 5.0 375kw beast.

Now that would be worth having.

The proposed 5.8 Hurricane / Boss engine is definately NOT Pusrod - as clarified in the Wikepedia article below. Importately the configuration goes back to a high reving oversquare 4 inch Bore x 3.5 Stroke (102mm x 89mm). Initially SOHC Like the 5.4 Modular (220/230) - with DOHC for high performance (XR8?)

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
