YOu can rotate the input shaft and count how many times the output shaft turns on each o the two transmissions. Since your interested in the top end, just put them both in high gear and start to count and rotate. Place a ":" between the number you come up with for the input and the output number and that should be your final drive ratio.

do you have to take the pulley off and the tire off ?

Not really. You may have to jack up both rear wheels or maybe just one rear wheel, depending on th type tranny and differential it has. Tires can stay on as can the belt that drives it as long as your able to turn the pulley. Make a mark on the tire at 6 o'clock, also mark the pulley so you can see the mark, rotate pulley and count the amaount of times it rotates until the tire makes one complete revolution and comes back so that the mark is at 6 o'clock again.

EX:
Pulley rotates 6 & 1/3 revolutions until the tire makes one revolution, it would be a 6.33:1 ratio

EX #2 Pulley rotates 3 times and tire rotates 1 time it wold be a 3:1 ratio and this would be a higher speed tranny than the 6.5:1 tranny. The lower the number the higher the gearing, and also the less torque is available unless you have excessive horsepoer to spare.
