After doing more reading it seems that any single groove big block pulley is the same for the 66-68 Hemi also. I have plenty of those laying around and will give it a shot.
Not so
None of the stock 383/440 water pump pulley, NONE of them are the same as the 1966 to 1971 street Hemi water pump pulleys
Many people, me included, have tried to use a stock 383 single groove water pump pulley with a 440 dampener and a 383/440 bottom single groove pulleys, they are absoulutely not comapatable on a 426 street Hemi motor
