What is the recommended carburetor for a Buick 430 running an Edelbrock B4B intake manifold? I assume Edelbrock right? But can I mount a Q-Jet. I had a spare carb from a 73 CAD 472 but I could not even get 2 holes lined up let alone that carb had bolts and my B4B intake has 4 threaded bolts inside the intake facing up. Thanks for reading my post.
