If you're talking about the 6.8L V10 Triton engine from Ford, it produces 365 horsepower. You may think "OMG! That's great for a gas engine!" but it only gets about 13 or 14 mpg average. But very reliable engine. :D
The Ford 6.8 liter V10 engine is 415 cubic inches Dodge has an 8.0 and 8.3L V10
It's a V-10 gasoline engine. Around 10-11 mpg city, 12-14 mpg highway.
Ford DOES make a V10 engine. It's a 6.8L V10 engine that is under the name of "Triton." So, it's a 6.8L Triton V10 engine. You can get the 6.8L Triton V10 in the Ford Super Duty trucks. The F-250, F-350, and the F-450/550 chassis cabs. But, as of Ford's new 2011 Super Duty, you can only get the V10 in the F-350 to F-550 chassis cab trucks with dual rear wheels. Fuel economy in the Triton V10 is somewhere around 10 mpg city and 14 to 16 mpg highway. That bad of mileage can be expected with a 10-cylinder engine and a heavy-duty work truck though. The Triton V10 is a very reliable engine, and I've worked on V10 Fords that have somewhere around a million miles. So, great engines but HUGE gas hogs!!!!
Straight pipes or some type of aftermarket exhaust will clear the emissions systems out and help the engine "breathe" better for better fuel economy. A K & N Cold Air Intake will help too. That also helps the engine breathe better. If you put these mods on a V10 your mileage would still be poor, but you'd get about 2 mpg better. Boosting the average V10 mileage of 11 mpg to 13 mpg. I used to have a 2001 F-350 V10. I got 11.5 mpg average with the truck stock. I used a K&N Cold Air Intake, True Dual Magnaflow Exhaust, and I SCT Tuned it and I achieved diesel-like power and got 14 mpg average. These V10s are reliable, powerful engines but the mileage is just extremely poor.
