yeah looks like the first poster to match up the Chevy 8.1 V-8 to The Ford V-10, gave specs for the 5.4 Liter Ford V-8 instead, but that is still pretty impressive considering the Chevy has 2.7 liters on the triton V-8.

if your gonna talk about fair comaprison through gearing then you have to account for weight also so you would need to add a 1000lbs to the chevy this is if were still comparing the 8.1 to the v10 motor and trans

I recently pulled my 10K trailer to Houston and back to DFW and got 12.5 mpg running about 65. The odometer just turned over 30K miles. The empty, combined mileage hasn't changed, though.
The internet rumor about these motors getting better with age appears to be true.

The warmer weather should help mpg also.
There is minimal difference between 4:10s and 4:30s. For some reason chevy puts tiny tires on their trucks compared to Ford some the final drive ratio more than likely still favored the chevy.
I'm running 265/75/16 on my Chevy with the 4:10 L/S and it will bbq the rear tires with the 8.1 engine. My 06 F-350 has the 5.4 and it's not even close to the Chevy. My friend with the 2V V-10 is a 4x2 as opposed to my 4x4. He's still scratching his with disbelief how my Chevy stomped him.
