Re: 2010 v8 falcon
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 
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
