Hey Jim & Chris,

Thanks for the response.

What I'm looking for is someone who can tell me the rpm range where the 235 operates the most efficiently. I guess you could call it the "sweet spot rpm" where the vacuum comes up and the little engine just kind of purrs along.
Every engine has this spot someplace over the power band. I was hoping to get a 235/T5 driver to give me some specific RPM's so I can make the adjustment before I lock in on the diff.

With max torque at 2000 rpm's I guess I'll just go with the 3.42 posi w/discs and keep the 3.73 in reserve.

Thanks again,

Dave
