So its 31 inches long from front to back, and 18 inches high from oil pan to top of valve cover... now when you say its measured from the oil pan "flange", do you mean that the motor is 18" from the bottom of the sump area to the top of the valve cover, or 18" from the raised area of the oil pan just behind the sump to the top, or 18" from the lower block surface where the oil pan bolts to, effectively making this the height without oil pan?

EDIT: I would also like to know if the 31" length includes the crank pulley or if that is just the block.
