RE: Are you sure that this........

The established standard is J228, Carburetor Airflow Reference Standards set by the Society of Automotive Engineers (SAE). This standard is a 1.5 inches vacuum for 4 BBL carburetors and a 3.0 inch vacuum for 1 and 2 BBL carburetors. This standard is followed by Holley and Edelbrock (and everybody else) except Pony Carbs to the best of my knowledge.

The standard method is to install the carburetor in the test fixture, create a 1.5 (or 3.0) inch vacuum with the throttle plate(s) open and measure the air flow. Adjust this air flow for standard barometric pressure (sea level) using established tables.

It has NOTHING to do with any engine, any camshaft or any head. Just the carburetor and the test stand. Go to your college library and look it up in the latest SAE Handbook (or even an old one the standard has not changed in any significant way for twenty years that I know of).
This thread, so far...
