well i would do this if it was mine. get really pissed off and pull it back out and not drive it anymore so that i can find out what the problem is and check all my clearances. and so ya know if you put forged pistons in and didnt check the clearance that sucks. its possible for them to be smaller or larger. did you assm the engine or did someone else? and for the rod knock it would get worse as the bearings got hammered down into an egg shape. it would knock slightly at a tade bit of throttle but really knock as you push it and also on decel but not as bad as accel.
so take it apart and figure out whats up because its not right. it will cost more if it puts a hole in the block.
