Steve, thats not a bad example of a good low rpm torque motor. Looks like max torque is around 4000 rpm, the lowest rpm noted on the chart. Max horse power is under 6000 rpm. I built my motor for a lower rpm and better torque but have never dynoed it. It too pulls nicely from about 2000 rpm, but it likes 2500 better. My max rpm is now around 6200, down from 7000 +! I also run a vacuum advance now, by the way. I get 10 mpg or better when I cruise it at about 65 mph and 2800 rpm, thats UP from the 6 mpg I got with the old 'monster' motor. I suspect cruising at 2000 rpm with a .6 OD would not result in better mpg or a happy motor in my case, but I could be wrong.

The hyd roller is a great setup for a lower rpm engine, I'm running a solid flat tappet myself.
