I did as suggested and disconnected and plugged the vacuum lines to the out boards, and the car runs fine, no lean bog. So it seems like it is the out boards. At cruise speeds the outboards open you can hear them but the car doesn't speed up. It's certainly a lean condition lack of adequate fuel when they open. All I did was transfer all 3 carbs from the 383 where they worked great to the 440. I thought they may have needed to be richened up so I added the Promax jet pates with 84 jets, and it still behaves the same. I'm stumped. Thanks to everyone for the suggestions.
