Yeah, keep wishin upon a star. lol I do know how to read the cast in date codes, so I can look. But like I said, I don't want to get rid of it if I do have one. That doesn't mean I won't take another 225 in trade if I do have one. All I care about it that it's a 225. I don't know why you're so hung up on this. A 225 is a 225 from 68 to 76 when they went to the cast crank and even then there aren't many differences. I'd understand better if you were looking for the exact engine. Then it makes more sense. There's no matching 71 engine except for ONE and your chances of winnin the powerball are better than finding THAT.
