Where does the 2013 GT 5.0 get the extra 8 horsepower?

Why in the world should I doubt Ford? Why would they go to the trouble of lying to the public about 8 hp? They made this change for cost savings, not to impress anyone or boost sales.

I'll let someone else punish you for your lack of reading comprehension.

Maybe we both are guilty of both comprehension (me) and not sending a clear message (otha guy)

It's just rated again. We all knew it makes more than 412hp. They're simply changing it on their brochures and advertisements. GM did the same thing with the 2012 V6 camaro. Made it 312 from 304 because the mustang has 305.
I doubt anything changed. It's always made that much anyways.

Um, no. We've proven the motor lost oil squirters and the pistons are revised, and speculate that the factory tune is revised to accommodate this. Take a second to read through this thread and find the facts.

Unless I'm completely misreading stevegt2012's post, he merely agreed that the motor wasn't actually making more power but was re-rated to be closer to reality...which by all tests that I have seen, is correct.
EDIT... ok, looking at what Steve quoted from the previous post, it might have been interpreted that the "SIMPLY re-rating" comment was meant to imply that they believed there were no other changes to the motor...which is silly at this point.
Anyway, it looks like the revised motor has a tiny bit more area under the power curve, which bench racers on the internets are starting to recognize as a possibly even more important measure of engine performance...at least as worthy of consideration as peak hp/torque numbers....but that the rating change was JUST a rating change and that there was no appreciable increase in peak power output.

It doesn't refute the observation that the motor is making nearly identical peak power with a different rating.

I believe the pistons are powdered coated and the oil cooling jets are deleted. The pistons are similar to the Boss minus the tune and manifold. It is friction which help give a slight boast in HP. Overall it is so slight it cannot be felt. 412 or 420 it is not a big deal and at the end of the day it is the driver who wins races not the 8 HP.
