Hey guys so I'm currently in the process of tearing down a m50tub25. Swap wise I pretty much understand everything and have a pretty good idea of what I need except for the rear diff. I'm mainly looking for pretty decent mpg as it is my daily. I know a 4.10 would make it fun but what kind of mpg would I get with a 3.73 would I be able to fit a 3.64?

This won't give you a MPG number but it will calculate the RPM you will be at.
