That might be pitch speed, but there is no reason to suspect the aircraft was actually going that speed, although they indicate that it could with sufficient power and low enough drag. Those rpm readings are reasonable. And measured prop pitch will mislead you, unless the airfoil is a flat blade, no camber, the true pitch is higher anyways.
Oh crap - looks like I spun the big end bushing. I know they need clearance but I should have done a better job checking. I have a Conquest billet rod, not the early cast rod, that may work.
