Tom, fuel pressure equalization is not a problem with the draw through carb. I am running an electric fuel pump though. When I ran a Harley S&S carb on motor it would only handle about 2 pounds pressure. I used a regulator that I modified with boost pressure on top of diaphram to give full fuel pressure under boost. I was worried that small float bowl would empty at high speed. I broke pistons 4 times at the drags before giving up and installing an AMC 401 in the 65 American. When I rebuilt the turbo 6 for my roadster I used a 4 bbl carb. After I finally sorted out a hesitation problem the 6 runs great now. Thanks for the compliment on my set up. Mike
