Old D/C Hustle Stuff Mechanical 6 Pack 4782/4783 carb build
I run those cabs on my 440-6 "Cuda. I like them much better than the vacuum secondary carbs. You'll probably want to put a wide band on it to help dial them in. Once set-up right, they are awesome! I had mine gone through at Promax and had Hughes deep port the intake. You just have to learn how to drive them, because even my 493 inch stroke doesn't like them mashed open at too low of an rpm. Well, actually in first or second it doesn't really matter.
I was going to use the fuel line in the second picture, but ended up going with three individual 6 AN's for more fuel flow.
