The reason I ask this is because I soon will be upgrading my differential from an 8.02 open-end to a 3.73 limited slip. (As soon as I get th new engine in). I was looking at a formula that was given to me and was tying to do the math, but I can't because I dont know what my trans ratio is. Example: Travelling at 70mph x 3.73(gear ratio) x .67(transmission ratio) x 336 / 27" (Tire diameter from concrete to top of tire) = 2176 Rpm. In order for me to complete this for my car (a 1968 with a trans from an 1985) I need the trans ratio from the 85. If ANYBODY eithe has this info or knows where to find it, please post it here...Thanks
