I've been using this cam for about 2 years and love the combo of gas mileage and low end torque. Here is what I have found after a couple years of tinkering..

It does not want to be at 750 rpm. Sometimes I go as high as 1000, but can get by with 900. Depends on how hard I run my alternator as to how I adjust my idle. This is with a brand new head from EB and a low end at 30 over as in my title.

I do find myself tinkering with the idle from season to season honestly, but I'm sold on the torque. For in town and interstate driving at about 3K it is perfect IMO. I've managed to pull almost 25 mpg on some trips where I've been between 55 and 60.
