Are WCFBs hard to find? I wish I knew more about them. From what i have read they were used on 283 Chevys also. IMHO the combo of a 302 and a carb in use from that period would be pretty cool. If anyone here ever ran one I would like to hear how it turned out. From reading at the GM heritage center the primary Venturi had a 1" diameter. Certinally in theory at least small enough for a good airflow siginal at low engine speeds. Airflow signal is one of the reasons that TLowe invented the "3 barrel", trying to move air fast enough to make the carb work more efficiently. If I had a stack of 4 bbl carbs I would gladly loan them to the OP to see what worked best. One question, how much carb does a 302 GMC need compared to the same size SBC or SBF? Jay
