"I have 1975 440B 330hp motors
"I have 1975 440B 330hp motors with Carter AFB carbs. I replaced the Carter carbs shortly after buying the boat last year as I had read good things about replacing Carters with Edelbrocks. I was cleaning out some stuff and decided to call some carb rebuilders to see if they would pay anything for theses cores. I read the model stamped on the carb(4613) and he told me that was a 1969 model for 383 V8, definitely not marine. Yikes! Glad I changed them out.
