Cool Recommendations on a rear gear ratio

Hi. My engine is a 351 Winsor, .30 over, forged pistons, balanced & blueprinted. Cam is 278 duration .478 intake and .498 exhaust. Running ported trick flow twisted wedge heads and RPM edelbrock manifold. I have a modified Holley 750 running annular front boosters and double downleg rear boosters. Last night I ran 13.9 et at 100 mph. I currently have 3.25 gears and a C-4 automatic with 1800 RPM stall converter.

I cross the quarter mile at about 3300 RPM in 3rd gear. I would like to use a rear end gear that will put me at 6,000 RPM in 3rd gear at end of the quarter mile.

Any suggestions on the right gear ratio. Any suggestions on a stall converter point to maximize launch? At 3,100 lbs, does anyone have a program to compute my rear wheel horsepower?

I am thinking 4.57 or 4.80 gears would be about right. But what are you guys running?

Try using the Analyzer to the top left of the screen. It should help you with both of your questions.
