so Mike did you see much difference using a staged 2bbl on a stock intake? How does that run vs. a larger Holley 2bbl?

I'm having and intake dilemna myself. Clifford 4bbl vs. offy 2X1 vs. progressive 2bbl or larger 2bbl on stock intake? Hood clearance and money are issues.

Right now i have a leaky 1bbl Rochester on stock intake with Fentons...on a '59 chevy.
