Not sure if anyone here will use this. But I stumbled a site that showed all the different gear ratios for the several transmisions. I threw it in an excel sheet and wrote some equations. Basically if you put in your Gear, Tire, Converter loss and RPM it will give you mph for both a locked and unlocked converter. Might be helpful to figure out what you need.

If you have a tranny you would like me to add, post the gear specs and I'll add it.

Added RPM vs MPH in 100 rpm increments. Put your info in the first page labeled "Top Speed"
