440 Automatic. What gears are you running?

Mild stroked 440. I have 28" tall m&h dot drag tires(bias ply) w/ 4:30's. Run on the street all the time. Ive even taking it on the New York State Thruway a few times. It is taching around 3500 at 55mph though.

Just reread this thread, who runs 55mph / more like 75-80 straight for the most part-------
