i wonder if whatever they do to bump a 6.1 to 500hp can be done to previous 6.1s.... but i wonder how they could increase power 75 horse without more displacement from the motor. the 5.7 going from 340 to 370ish seems more reasonable than 425 to 500 without a larger motor. i could be wrong, or maybe there is something in these motors being held back, that we havent been able to access yet.
