With the 4:10s on the auto how many rpms does it turn at 80 mph at what would be the top speed? I am considering 4:10s when the car gets here and I just wanted to see what you guys thought.
The stick car has .68 overdrive and the auto has .71. I'm turning about 2800 or so at 75. They really pull strong in my Auto. I just baught the Steeda cold air kit and it sounds great with my foot in it. Steeda says they are getting 13.20 out of the re-burn and their cold air kit. The 4.10's should do a little better.
