Our Dart at over 3200 #s ran 10.90s @ 119 with a 9.25 to 1 360 with J heads that I built. I ran a 4.56 gear and a 5000 stall. My 60 foot times averaged 1.44 and my timing was set at 35 degrees . I ran an M-1 manifold and a BG 825 carb. What really helps is the 904 trans with a 2.77 first gear. In 2007 I built a stroker that now runs 10.0s.
