Mopar 413/426 Max Wedge block casting number confusion

33IMP said
Per Greg Lane, 413 maxwedge blocks were 1852029. Stronger than the passenger 413 block #2120529.
Max blocks have: AAQA front of the driver's side bank, notches on the exhaust side of the cylinder bore, to clear max exhaust valves. and a different font and stamping size than normal (distinctive).
In 63, supposedly some of the 413 max blocks got drilled to 426 bore, but the great majority were 2406730. Mine is a 730
Pics of real max block follow.....

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.
