1964 426 wedge

I can look at the pad. If a prospective buyer has questions they can call the shop. I was not implying that it was a max wedge only that the casting number indicates what it does. No one is trying to pass this off as anything. It is a 426 wedge that is ready to drop into the bay of someone's ride. Yes the owner says it is special because he has building Mopars a very long time and rarely comes across them.
I gotcha. I just have a thing for max wedges and if it's truely a max wedge block, that's significant enough to get me to look deeper at it. I've got an original 413 max wedge block, complete with the notches, AAQA and the casting number. But it's missing the top end sadly.
