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.
