Had a flat on the way home yesterday, so that put me behind the rest of the evening...didn't really have time to expound.
But here's my thoughts on this:
You don't cruise at 3000-3500. You cruise at 1800-2500. Dynos generally won't pull down that far, so if you're wanting a good realistic view of what's going on as you're going 60-70 mph down the highway, I don't think it would be easy or prudent to go there.
If I were an independent dyno operator, I would decline at someone's request to pull it down that far, even if I were able to. As I mentioned earlier, you don't always know what the compression ratio is, what the cam is, what the timing is, etc. You get an engine pushing 11:1 with a short cam, too much total timing, and a quick curve, and I think it would be rattle city if you tried to lug it at wide open throttle at low rpms.
A pull from 3500 will tell you everything you need to know, unless you're building an engine for your RV or dump truck.
