Gear vs speed chart found.

Found a good one.
gear/tier size/transmission calculators by 100 rpm increments

Now to get expressed as a graph with the torque hp curves matched for each gear . Had Gran Turismo 3 in Iraq when you upgraded the car to the full customers customizable transmission you could actually monkey with each gears individual numerical value and was a nice graphic
I guess I could hand plot all this

Results fom link

I ran the #'s out to 4200 as that is the $$$ red line.
With the 3500 governor spring kit 135 @100% transfer is possible with a 31.7(stock size) 3.55 :1 (stock)
155mph @3500 with3.00.

Take the 6% diminstrated losses (possible warn 2500 governor spring contribution.) And that is 126.9 , 145.7 respectively
