Yes, It is a new rebuild. I turned it be hand (socket and breaker bar), to put it both in time and to turn the crank when I was priming the oil pump. The transmission was already hooked to the motor including the flexplate and torque converter. The only thing I added after I turned the motor by hand was the radiator and dist. and wires. I didn't check it tonight, but I don't know why or how it could have locked up since then. (I timed it on Memorial Day weekend.)
