    ...that above estimates included lots of NOS stickers... very accurate numbers
    blown transmissions are about as useful as 97% of the guys on this forum

    No think it was 514.7hp to be exact.. it also had headers, ran it with 93 octane, and it was on the 3rd run of the new tune. So it might have picked up a little more as it learned the motor.

    i dont think the stock internals would be a good idea over 500 hp.

    surfing the net I found this......not that far from my goal

    2010 Camaro SS + boltons + cam = 505 rwhp - DFWstangs Forums

    In the video there is a too much choppy idle, I will settle for a little less. So 480WHP will be sweet !!!!
