Does it have oil? Long time ago my car made a knocking noise I had an oil leak come to find it was near empty.
or Could be valves tapping.

That sounds exactly like a spun rod bearing. Did you Plastigate all of the bearings before you bolted it all together? And did you use the right undersize bearings?

pull the motor and start over, it could be the wrong bearings or it could be the wrist pins slapping around
