I have a 73 Duster that used to have a 380hp crate motor in it. It had a 9 inch converter, 3.91 gears, Holley 750dp, and a race weight of 3310lbs. The best it ran was 12.30's.
thanks for replying. That type of ET is what I am expecting and would be happy with. Just curious, what was the shift point on your engine? Mine revs quick to 5500 but falls flat after that.
