All I know is that ford built the blocks for the racing team in the same plants they built blocks for the public, and they did have some pretty crude way's of ID'ing them. I do know that they had purpose for scratching mark's on the block's though & found out the "C" was for Cobra, the "A" was a Police Interceptor & the XX was for I don't know? I have emailed & asked around a little, but so far my question's haven't found the right person yet? Patience is a virtue..........isn't it? The fun is in the journey, I mean how many times do you get to search out a mystery in life, that's actually fun?
