Demon makes 2 styles of carb now, the Holley copy and the Carter copy. I don't think anyone trying to follow this discussion knows which type Demon you are talking about.
I went to the link address and saw the one he is looking at.
The design is close to Edelbrock in that the bowls are within the square area right above the intake mounting just like an Eddie, but the composite body could only help.
The original Holley design is way better about fuel boiling because the bowls are hanging out there in the air.
