Look again. The chart says multiply your axle ratio by transmission first gear ratio. Your torqueflite has a 2.54 first gear, so 3.23 x 2.54 = 8.20
The chart, I'm sure, provides the "ultimate" gear ratio for acceleration from a standing start and doesn't mention tire size, which is a factor among many others...
This is useless information for your fat Chrysler... it's built for smooth, luxurious comfort, not neck-snapping stoplight launches.
.
Here's a really good calculator for finding out the desired rpm and tire size.

My “fat Chrysler” is far from what your thinking of so this info would actually be useful as a point of reference. Thanks for pointing out my mistake though.
