    I'm not good enough to throw out a number.
    I will say.
    Good enough to make the cut for GSR.

    Full port work is more likely to be in the 360,370's.Bruno.

    My conservative guess would be 600-625hp but it's not a very educated guess.
    Based on a motor I have with Stage2 SE's and a roller with a bit more lift but probably not as much flow. It was at 605 TQ at 4800 and 605HP at 6500.
