What will my 68 Dart 408 run in 1/4 mile?

the gears are going to be the biggest problem.

I have a similar combo with an overdrive. I have 4.56 gears. I run low 11.70@114 in 3rd, 12.20's in OD.

I'm guessing you'll go 12's

I ran an O.D 833 in Dart Sport and loved it ! 4.10s and I could cruise the hwy then race 1-3... cut some 1.60 60fts and high 12s with a mild 340 build.
90% Street driving so I didnt mind the 1-2 gap.
