Dying to see how you make out with your motor in Calvin car, I know it'll take some runs to get everything sorted out.

The upper rod bearings are proberbly beat to death in that motor. Running straight pump fuel, at rpm is asking for trouble. They should have started out with race gas and diluted it down watching the plugs. A motor at cranking pressure is a whole different animal at RPM with a big cam, overlap can kill ya on the upper end of RPM. It will send compression through the roof. I would like to see pics of the rod bearings after they pull them. How fast was he turning it, being a new motor, and how tight were the rod and main clearances?

carb/electrical/ignition issue...that will do it.
