Sorry for the late reply, I got really busy at work the rest of the day yesterday and I just got a chance to respond
my carb is a LIST 3310-1
I forget if its either a 750 or 780 cfm. The carb belonged to my father who had it mounted on his '70 cuda 383 4 speed that he daily drove from '74 until '93. He said he never touched the carb once the entire time he had it and it never gave him any issues. My brother had the carb professionally rebuilt in the early 2000's in the hopes of getting the 'cuda back on the road but he never touched it after it came back from the shop.
I havent had a chance to pull a couple plugs yet to check their condition. When I do I will take a picture of them and upload to let you guys "read" them for yourselves
