Yes, but being someone who's ran both blocks I can say they are the same butt dyno wise and they dyno the same. Dyno Jet, Mustang, SAE and no matter the fact think about it like this... If their was a revised tune dont you think their would be a Tsb reflash? Ive seen 13s eat 12s/11s and vise versus . I think the up-rating on the Hp#s was a compensation on Ford's under rating the car to begin with.
