I am experiencing a bog/miss at low RPM when my car is in gear. A friend of mine tells me that I should install a spacer between my intake and carb. It is a SBC with a mild cam, I already have a high rise intake on it. Oh, and another issue would be hood clearance if a spacer will solve that issue. The intake and carb are brand new. I am thinking maybe the accelerator pump. Any advise would be appreciated.
