need help decoding this engine...
So I was looking to see the engine configuration on my truck and I cant seem to find out what it is. The casting on the drivers rear is 3970010 which means it is a 68-72 motor but the engine code info on the front dosent match anything. The number stamped on the water pump boss is V111CTYY and there is a partial vin code (which dosent match the truck... not surprised) but the only thing I found that said CTY says its a 400?

Welding is a lot like sex, you don't have to be great with the rod as long as you thoroughly prep the surface and your good at grinding
