Slant Six Carburetor Choices

I have the Quick Fuel 450 vacuum secondary on Vixen. It runs extremely well. I like how it has all the screw in air bleeds and idle feed restrictors so you can really zero in on the tune.........and I have. After I put the header on it, I am confident it will suck down a 600 double pumper and if I get one, it'll be a Quick Fuel for the same great adjustability.
