My guess would be 3:42. I have 3:42 in my 66 305/350 with 28" rear tires 2200 2300 was 65mph.Quote:

Dedending on how tight or loose the convertor is it would be in the 3.00-3.10 range.
dlotraf33 you might want to check your tach, speedometer or gear ratio. With the 28 inch tall tire and 3.42 gear your RPM at 65 would be in the 2700 RPM range (2668 RPM without any convertor slippage taken into account).
thanks for the input guys.I'm sure ther's a formula to get really close on the gears but i had no idea where to find it.thanks again.
Here are the links to the calculators I most use. It's the place I start almost all of my builds.

Gear Ratio http://www.mustangii.net/gear_ratio.asp

This link has pretty much any kind of formula you would ever want including the one your asking for:
