Mopar 413/426 Max Wedge block casting number confusion

Love to see the car too .

I have a real 1962, 413 max wedge, block only. It’s totally a boat anchor. Too rusted really to do anything with. Thing was storied by the previous owner, apart, on a dirt floor barn . It was sank in the dirt half way down to the valley.
It's out of the car at the moment, but the car is just a slant six 62 savoy originally. Currently, a 440.
I got the max in a straight across trade, carbs to pan, for a 1968 Z28 302 with the right casting numbers.
