lowering 60 foot time

When we had the 383 in my sons Dart its best 60 was a 1.77 on the old springs and air shocks. It did hook and had a Turbo Action 10" tight 3000 convertor and 3.91's with 26" McCreary tires. Its best et was 12.31 @ 110 and 7.86 @ 88. We never really worked on the 60's much but yours aren't all that bad for a mild street car. Also check the pinion angle as that can help some. Ron
