Engine Number - The Rocket engine unit number on full-size models is stamped on a pad on the left (driver's side) cylinder head, directly beneath the rocker arm cover lip, in between the 3rd and 5th spark plugs. All full-size model engines have a displacement of 394 cubic inches. Full-size engine unit starting numbers begin at 300001.
