You probably should determine your current axle ratio for certain before doing any swaps.

Jack up one rear wheel.

Put a chalk mark on the jacked up tire and a board with a finish nail in it pointing exactly at the chalk mark.

Take out your spark plugs. Put the trans in high.

Take any slack out of the drive train with the crank (make sure you didn't move the elevated rear tire)

Mark exactly where the crank is.

Turn the crank until the tire has turned exactly 2 revolutions.

The number of times you had to turn the crank to get those 2 tire revolutions is your gear ratio (4 times=4.11/1...3 3/4 times=3.78...3 1/2 times=3.54)
