I don't understand what kind of validation you're wanting here.

Displacement doesn't matter, except in the fact that some dynos have trouble offering sufficient torque to hold big stump pullers....thus Barry's comment on water pressure and big torque engines.

What does matter is compression ratios, cams, ignition timing, combustion chamber shape, etc, etc.

I told you that I built a 408W that was less than 9.5:1, had about 7.5:1 DCR, a slower ignition curve, EFI, etc. that I wouldn't mind to pull down to 2500 or so. However, that was essentially a *truck* engine, designed for towing/hauling.

I don't understand the extreme desire to see what your engine does at very low rpms. Actually, I'd like you to tell me why, because to everyone else, it just really doesn't matter unless you're towing a load. If you're cruising at that rpm, you're not at WOT. If you're at WOT throttle at rpm, you're just there for an instant. And again, WOT on the road is nowhere near WOT on a dyno!
