Drag Race Advice Needed

If you’re going to buy a trans, stick with a 727 and use Cope or A&A. The 512’s don’t need a crazy gear unless you run a really tall tire. If you’re using a 28” range tire I’d use a 4.10. with a Dana. Like mentioned a 3.91 would work well to if you run a 8.75. Not a fan of ratchet shifters myself. All 3 mopars out in the garage have cheetah scs shifters. The cable enters from the rear so it avoids the burnt cable bs. Also easy to use for a street car. Put the shifter in the gear you want. A properly built 512 will easily run 10’s in an “A” body on pump gas if you use the right heads and cam.
