Same answer I posted to your question on the other forum.....
What would I do?
I'd send the Q-Jet to Cliff Ruggles to be tweaked for my motor. Then I'd bolt in on an Edelbrock Performer RPM Q-JET #7104 intake manifold.
In my opinion, there is no better carburetor to meter fuel for an internal combustion engine than the Rochester Quadrajet.
