yep. 383's got 'em too. i have a set still on the shelf from a 15k, 69 engine that looks like new. that set was taken out when this particular engine was "day two'ed", headers, dp4b intake/780 holley, racer brown ssh25 cam, roller chain and re-curved distributor. my 66 charger had that set as well. it went by,by with ???k, so i replaced it with a 413. that inland shifter sucked. was replaced with a hurst comp+, but i quickly found out i can't shift for s**t. these were "back in the day" when these cars were almost new.
