    Chris I was guessing 430 and was hoping 450, can't believe it was 475 standard. The correction method is so you can compare to others but even with SAE standards it was over 450hp. All the while having accessories and stock exhaust. I port matched the intake and the 190cc heads sure do wake up the sbf. I can't wait to see how it feels on the street.
    I also hadnt mentioned it but a spacer below the fitech creates volume and tunes the intake from the research I have done. I think it picks up 10-15 hp compared to other volumes. Its about matching the tune and pulses of the valve train. Its all in the combo and I did my homework.
