I'm having trouble finding a 3.73 gear, could I get the same result out of a 2.28 in first gear ? Currently I'm running a 3.42 and topping out at 5200 rpms. Can't touch the competition on the straights.
I tried smaller tires ,but it doesn't help much.

to find final drive, multiply transmission ratio by rear-end ratio. do this with your 3.42. then do the same with the 2.28 with low gear ratio. (keep in mind that the higher the ratio, the lower the gear) if the 2.28 final drive comes out lower, it may help some. look on ebay. there are always gears for sale. on ebay, "search" for 7.5 gm or 8.5 gm (for example). (assuming you're running a chevrolet) hope this makes sense.

My question really is, can I get more speed if I switch to the 2.28? without pushing too many rpms?
