Thank you very much for all the replies!

So here is the rest of the story.........

The BLP body was not legal in his class so he had to send the carb back to Gary Williams to get a Holley main body put back on it (cost another $300 and Gary kept the BLP body - he has done those shenanigans to me too).

So below is a picture of how the carb sits today. Looks like its a 2 circuit but I am not familiar with those bleeds - look a lot different than my Dominator ones. What are these bleeds?

Would think it would still be a good carb - agree?

They used to run Dominators but found that the smaller 4150 carbs were more responsive during restarts.
