This leads me to a question, I currently have 3.73s in a Dana 60, would the jump to 4.10s be substantial? Currently have an OD trans.
3.73 divided by 4.10= 9.01 % according to my calaculator
I tried using 3.73 then 3.91, then 4.10 and finally 4.30 I my old pump gas Duster, very little differences in ET and MPH in the 1/4 mile.
I ended up bending the heck out of the 8 3/4 housing and put a truck Dana 60 cut down with 4.10, I ran both the M/T 325x60x15 ET Street radials and the M/T 10.5x31x15W slicks on 10 and 12 inch wide rims at the track with no real differences in that car on either set
