When you look at the engine mods vs. the horsepower rating, it's obvious this engine is capable of more than 440hp and 7,500 rpm. They could have done that with minimal mods to the existing 5.0. This is essentially a 302R motor.

Just what the "red key" does, and what the final power ratings will be is anyones guess, but I think it's safe to say 440 is a conservative number.
