355 gears. Or more ?

I run 4:10s in the rear with 28 x 13.50 tire, at 60 MPH, RPM is around 3400.
Like you my Dart was always spun up pretty good, as I ran 4.56 on the street and strip with a 28.4 tire and it was far from pleasant at 60 mph, became kind of hypnotic after awhile.
Wife’s Challenger ran high 11s with a 3.91 short shifting at 5,000 and letting up a bit in high gear.
I had it leaned out when I drove to the Nats, forgot to change the springs.
