no. Normally an original Automatic wasn't drilled. I never saw an original 318 auto drilled, or a 383 auto, regardless of application. The best way to find one is to know the depth, and measure the subject you come across. Until 1990 or so all the crank kits I bought were drilled as part of the rebuilding of the crank at NAPA, or wherever. It was easier for the rebuild companies back then to sell one crank for each engine application. However, I can't get them anymore and I don't know about anyone else. RoJam won't even drill them for me anymore.
Now I stock the cranks that are drilled whenever I find them. For some unknown reason, the last group of 440's I have found have all been drilled. (67-74) A Mystery, HP or not. The 74' is an original 440 HP and forged crank, removed from a 74' Charger in 1984. you may get lucky and find one that has been rebuilt, and have a drilled crank.
