Remember how we told you about those leaks from the Ford dealer conference earlier this month indicated the 2010 Ford F-150 would get that shiny new 4.4L V8 diesel engine? Well, spy photog to the car and truck stars, Brenda Priddy, claims she's got this photo of a 2010.5 (that half means it's either half the truck Ford thinks it is or it means it'll be a mid-model year refresh) Ford F-150 mule with that big, new diesel under the hood. Why does she think it's the diesel engine mule? Well, it's those tell-tale dual exhausts, that's how. Full report from Priddy after the jump. (UPDATE: Those truck-loving folks at PickupTruck.com have more diesel F-150 pics that include a 2009 F-150 front on a last-gen body and the seven-lug wheels that indicate the Heavy Duty Payload Package may be an optiion in 2010.)

Scoop: Ford's 2010.5 F150 Diesel.... Sources at Ford's recent dealer's meeting recently revealed plans for a 4.4-liter V8 diesel, and we caught the first mules earlier today! The dual exhaust off to the side is the number one give-a-way to the true identity of this test mule. Our spies are telling us to expect about 340-horsepower and (and torque at 430 lb-ft.). After the launch of the 4.4-liter in the F150, the powerplant will appear in the Expedition, Navigator, E-Series Vans and Super Duty trucks. Photo Credit: Brian Williams for Brenda Priddy & Company
