No, I'm very shure, I just looked at it again and it is 2488130-12 and its on both sides of the engine, and was made in 1-18-67 and can find any other #s. I'll try to up load pic.
Yeah! I got under the car with a light and a magnifying glass, and you right it is 2468130-12 do you know what that (12) stands for? I might need new glasses!
Look up Mopar Core Casting Index Number, you'll find a better explanation than I can give you. It has something to do with the number of times the casting core was used for the cylinders.
