That would account for a few percent of the difference between the two. I keep hearing people say "GM under-rates their engines" and I think it's just they rate them as net and not gross. I am very interested to see how this Mustang performs. Love them or hate them, you got to hand it to Ford. It took some stones to go for broke like this. Hope that thing stays together...

The new motor is to J1349 and so was the 5.4.
Also as of 2005 if a manufacturer claims to be SAE certified is has to use a third party.
