Big Block Mopar Low Deck Offenhauser Dual Quads Complete AFB Carburators

I bought the car with this set up on it. The car never really was used just sat for years so the carbs needed a full rebuild. I'm a Holley carb guy never had worked with this style so I had the Local carb man Chassis dyno tuner dip and fully rebuild the carburators in April of 2012.
I removed the intake and sand blasted being careful not to hit any of the flanges or mounting areas and reinstalled it on the engine.
My motor is too mild for the set up. a 1972 400 freshened up with a slight cam and headers.
Just too rich. I was advsed by the carb man when dynoing to put a Edelbrock intake and a 700 or 750 Holley for my application once seeing the #'s.
It really ran good but it wouls load up when city traffic and if you did'nt get on it once and awile.
A progresive linkage would have helped but between the rebuilds, all new air cleaners, heim joints and gaskets I just did'nt want to put anymore cash into it.
I'm over $500 into it.
Thanks,
Mike Z.
