Looking for a 1971 slant six 225

I'm not sure about the date code. If I remember, it's something to do with the stamp on the lip behind the coil. I'll have to look into that and get back to you.

Regarding the year, I was hoping for a complete and correct drop-in engine, or one that was "running when pulled" 20 years ago, so it doesn't need too much piecing together...
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.
