Mopar 413/426 Max Wedge block casting number confusion

Brooks James said

Appreciate your opinion, it may not be, but all outward markings on the block , that can be seen topside (paint over pad) would indicate a max, which is great for me as I want to build a 63 Savoy 426 max wedge.clone. If someone shows up with a borescope or mirror, they won't get near the car, lol
So... Any way you slice it, I'm happy

Depending on how accurate you want to make your 63 max clone.....
you would want the pad to look something like mine, in pic#10 in your other max thread. (A late 62 built for a 63 426 stage one motor)
You will also need some four bolt valve cover max heads, for either a 426 stage 1, or stage two.
The 64s were the first with six bolt covers.
