New engine gremlins - frustrating

IMHO, that cam is not going to be all that torquey at low RPM's. At 20 mph, and the TC locked, then engine would be turning around 2600 RPM, assuming a 3.55 rear gear so it is making sense that things are starting to work at that speed; the cam is getting up on the curve.

Got any piston info for the new engine? CR is unknown at this point.
