but thank you non the less

I really wasnt trying to be an ass. i came up with that number using this sites calculator. I just took the RPM for 75 with 3.73's and 4.10's and averaged it, since the 3.90's are pretty close to between the two. The 2550 rpm I posted above might be off a little, and it could vary depending on the size of tire you are running, but it should be pretty close.
