[Chevelle-List] Carb and Headers

[Craig & Cerena Robertson]

My intake has a 600 Holley Carb, which I'm told is going to be to small for my 396 engine.  The guy working on my engine suggested a 650 or 750 Double pumper or a 750 or 780 secondary Vac (I think that was the term he used).   Can anyone give me some pros and cons of each.  I am also going to install headers, any recommendations.  Thanks   Craig 69SS
