Anyways, getting to the point, turns out it was a 413. Casting number is "1852029-2" then below that is cast "RL". The stamp pad by the distributor reads "S41" and "8-14" Now from what little info I've found myself, I find that this is a 1962 413 Max wedge block? Is that right? Or is this just the garden variety 1962 413? There is a non original set of heads on it, so no help from those. Any info you guys can provide would be appreciated. Thanks! Happy new year!

Sorry, the 1852029-2 was just a truck block, used as the basis for max wedge motors because it was stronger than the car block. But technically it could be a max wedge block , because it is a truck block. A "real, OEM" max wedge short block would have 11 or 13:1 pistons and solid lifters as well as a few oiling mods, which I am unclear about, as well as notched cylinders for the larger 1.88 exhaust valve and 2 different fonts in the stampings. The truck blocks were higher in nickle and were thicker cast. As quoted:
" 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. "...
