Anything is possible back then. But this is why most professionals documenting and verifying these max wedge cars go by the rule of three, that being the casting number, the AAQA, and the notches. The dizzy pad usually is looked at after those three because it’s easy to stamp a dizzy pad. Much harder to take a casting number.
Plus, after they left casting, the blocks for max wedges were sent to a special performance engine division to build out. Some blocks were rejected for various flaws that later were corrected and reused elsewhere. So it’s not uncommon to have one with the right casting number but not notches or dizzy pad information.
