Venom - Assuming you have the original 8.5” 10-bolt rear, you can get new 3.08 gears from several sources. Also, assuming you have 26” tall tires that allows 776 revs per mile x 3.08 = 2391.5 rpm at 60 mph. Divide by 6 to get rev’s/10 mph increments x 7.5 (for 75 mph) = 2989.4 rpm. If you can source 2.73 gears (I don’t think there are any choices in between) they would drop the rpm at 75 mph to 2650 rpm. Taller tires would drop the rpm a little bit.
