My Ranchero has a 351 in it and I am trying to find out if it is a Windsor or Modified, 351w or 351m. I have been to the Motorcraft/Ford website and it does not support pre 81 vehicles. The sticker on the drivers door jam was painted over by the previous owner. I can read a few of the numbers on it, but not all or what they stand for.
