6.2L HP & Torque Difference
Does anyone know why the 6.2 in the F150 is rated at 411HP and 434 FTLB's torque and the 6.2 in the F250 is rated at 385HP and 404 FTLB's torque. You would think that with the heavier duty truck in the F250, that Ford would have it reversed.

Different cams and a couple other small changes. That was done to increase power for the Raptor SVT off road truck. Kind of sucks that the get rid of the torquey V10 in the pickups, and the the Super duty doesn't even get the better version of the 6.2.

Not the same, with premium fuel adds about 10 HP according to Mike the factory engineer. More of the power is gained from the Raptor cams & other changes.

The power numbers are larger in the light-duty pickup for two reasons, according to Chris Brewer, Super Duty chief engineer. "The main reason is that when the truck goes over 8,500 pounds [gross vehicle weight rating], the SAE [horsepower and torque] rating method changes," Brewer said. "We can't get the same horsepower and torque out of it [like we can in the F-150].” The 6.2-liter V-8 in the Super Duty also uses a different camshaft from the light-duty version, which, some may recall, is the same approach Ford uses to make 500 hp in the FR Raptor XT version of the 6.2-liter V-8.

LS2 already pointed out the cam differences. I wanted to add that according to a Pickuptrucks.com article the chief engineer attributes most of the difference to rating differences in the over 8500GVWR class. Reminds me of Chevy rating their 6.0L lower in the 3500 than in the 1500.

To clarify that further, the engine is the SAME whether under or over 10,000GVW, only the power levels are read at different RPM levels; 4179 RPM for over 10,000GVW, and the actual peak power level RPMs for under 10,000GVW; the difference being, noise regulations are different for the different GVW levels. You get the same engine either way; they are only measured differently.
