RE: 413 block casting / serial number decode help

[sean dietz <dietz_diggler@xxxxxxxxx>]

In 1962 the max wedge used a block casting number
1852029. This was a truck block that was stronger than
the passenger car casting, number 2120529. I have
never compared the two casting number blocks side by
side but I have been told the truck blocks were
thicker casting making them a stronger block. The
other thing I hear all the time is the 029 blocks were
higher in nickel content adding strength. Original max
wedge blocks will have a machined notch at the top of
the cylinder bores on the exhaust valve side to
accommodate the larger 1.88 exhaust valve. Without
this notch, the valve would hit the block. Original
max wedge blocks use two different size punch sets for
stamping the identification numbers on the engine pad.
The fonts are different for the punches as well as the
abbreviations for engine size and performance level
are different from regular passenger car engines of
the same cubic inch. 

this info was copied and pasted, i got it from
maxwedge.com, i got curious when i looked up your
block # 1852029 and came up w/ a 426 reference instead
of 413 on mopar.com. dont know if this will confuse
matters more, but i'm going to look into it some more
for you. send me an im. do you have dished pistons???
or flat? anyways keep us updated. Sean Dietz
