Don't know if this is a racing post or not, but...

I don't know.
I didn't see what gears you are running back there, and was too lazy to hunt it up,lol
If you have 2.08s then the math is right.
If you don't, my memory could be wrong on the 42 o/d ratio
But if my numbers are right and you have 2.45s say, the math spits out 1421 in lock-up, with 26s,
