looking for help on a 519 block that came in a 59.I know it is not right for the car but can not find what it is out of. The stamp on the front is v145019.I was told that the letter v indicated that it is a flint block for 1967year but as far as I know there were no 519 blocks in that year.There is a 1/8 tap plug on the front of the block above the timing cover .any help would be appreciated,thanks,norm
