In 1967 there were two 289 engines used, a two barrel carburetor version and four barrel carburetor version. The two barrel was identified in the VIN as a 'C' in the 5th position, the four barrel was identified as an 'A'. (If you got a 'K' in that slot, let me know, it's a rare 3rd version.) The block's casting part number and date code are located behind the starting motor's location. If you have a true 67 block, it will have a casting part number of C5AE-6015-A or C8AE-6015-C (rare). The next bunch of characters are the actual casting date, and they are located nearby (Ford was not neat) the casting part number. In your case, it would be either a 6 or a 7 (the year) followed by a letter representing the month (A=Jan, B=Feb, C=Mar, etc thru M=Dec) and a number for the day (1 thru 28,29,30 or 31). On the driver's side of the engine, on the front, there is an extention that is used to attach the water pump to the block thru the timing cover. It should have the engin's assembly date (same format as the casting date) plus the inspector's ID. See the picture (it's not my engine, I couldn't find the damn pictures of mine). In 1968, the Feds required a VIN number to be stamped on each block.
