1956 374's should have a number located exactly where RB indicates and should start out as 56XX where XX > 79. If the XX < 80 then it is a 352. If it starts out with a 55xx instead of 56 then it is a 1955 motor and a 352 or 320.

Edit: if it is a factory replacement engine then just about anything or nothing mite be stamped there.
