So I am trying to figure out what rear end to pick up for my 49' 3100. I know their are a wide variety of rear end options out there. Planning on a ford 9" rear end. 6l80e trans. 28.5" tall tires with a 500+ Hp 5.3l.

6l80e Trans gearing.

4.027
2.364
1.532
1.152
0.852
0.667


So I'm leaning towards 2.72 to 3.25 rear end. I compared everything to the icon thrift master. They are running about a 5.6 sec 0-60.
I am not sure where I want to be with the ratios. I just know I want it to be quick. I've been searching online and there just isn't much of a chart out there telling you want gear ratios are available. How does someone figure out what gear ratios are out there to choose from? Leaning right now towards a 3.00 but what else is available and should I do something different?
