Does anyone know what your average '68 QJet off of a firebird 400 flows? Just curious whether to keep the Q Jet or go to a Holley Double Pumper for my 400/455 Street Strip motor. And what is better the original 4 barrel intake or an Edelbrock Performer Intake?

The Q-jet flows at 750 cfm and the only difference between the factory intake and the Edelbrock Performer is weight but I myself prefer the factory intake to the Edelbrock.

Is there a specific reason you prefer the stock intake to the edelbrock?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
