I have a 27" tall tire and 3.73 gears. What speedo gear should I use. The archives show 3.55 and 3.91 only of course.

You might put a piece of flat stock on top of one of your rear tires & measure the EXACT distance to ground. Tire mfr listed heights are usually not dead on accurate & this could tip you one way or the other on which pinion gear to select.

If the circumference dimention makes a more accurate read for this then I will start doing that & not recommending checking the height. I did use the piece of stock to get the height on my 65 dart to select the pinion gear & it's dead on but yeah the stackup of tolerances as in the tire dimention may have just worked out in my favor in this case.
