3904392 - this is the casting number for the 67 2.19/1.88 106cc L-88/L-89 Aluminum Rectangular port.
3935439 - this is the casting number for a 427 block, 2 or 4 bolt mains. Could be a 390/400/430/435hp engine.
What is stamped on the engine pad and what are the casting dates of the block and heads?
