Justin, what converter do you have and where do you shift? You know my old Dart , with the stroker I was shifting at 64-6500 and trapping at 6600, this with an 8" race verter that flashed to 5200. I ran a 4.10 gear with it and a 30" tire. Best 60 ft was 1.43, best 1/8 mi was 6.59 @ 104, best 1/4 was 10.45 @ 127.
