What I found with my IDI, keeping it at or a little above 2500 rpm while towing, there was never an issue with pulling a hill, mind you I was also pushing 13-14 psi at said rpm under load, so, it was making pretty good power too. Oddly enough, even spinning 2500 all the time, the thing still got good mileage.
However, any IH application I have driven with an IDI generally runs 24-2500 rpm at it's designed cruise speed. I'm thinking there's a reason for that.
