ok this is what i got
3.73 gears,
70mph 2200
80mph 2500
90mph 2800

4.10 gears
70mph 2410
80mph 2755
90mph 3099

i did this with my automotive math book, so the numbers should be really close. i had to guess on the overdrive gear ratio though. i put in a .75 final drive and that got me where i wanted it too. pretty close anyway.
hope this helps

I think .75 is just about dead on from what I remember about the data I pulled from my tranny one time...either .74 .or .75...something like that.
