I have a 1965 mustang and im planning on replacing my old 2 bbl carb and replacing my old intake manifold. I want a 4 bbl thats reliable enough to be a daily driver. What do you guys think would be a good setup?
depending on the level of modification you are planning for your 289 it goes like this;
stock or mild build; performer or weiand action plus intake with an edelbrock 500 or road demon 525 cfm carb.
mild to moderate build; performer rpm or weiand stealth with a carb as above.
next step up from the above; a 600 cfm carb from edlebrock, holley, or barry grant(the demon series carbs).
after that you move into the single plane intake range with the victor jr, or an older torker intake, or the weiand equivelant intake, and carb size can move into the 750cfm range.
