30 over 1964 426 wedge block and crank. Has minor crank between freeze plugs on passenger side, Can be brazed. Was cleaned, bored and the sat. Bore is good. $300
Casting number (ending in 730) for a '64 max block is same as street wedge block so no help.
This was cast of 15th Aug '63 so appropriate for a '64 assembled mill.
Max blocks all had AAQA cast into drivers side front face, but so did some other street wedge blocks as I think this does.
Max blocks had exhaust valve reliefs machined into top of each cyl bore (can't see if there in OPs small pics..)
Max blocks had unique ID pad stampings and in a unique font too (i.e. LC or HC, which this does not have and the font here is standard Chrysler).
V42. V = 1964 42 = 426
10 10 HP = assembled on 10th Oct and was a HP engine.
So this block is from a 1964 426 "street wedge" (factory rated 365HP).
