I decided to go with an AFB so up for sale is a very nice Rochester 4GC 4-jet, 4-Barrel Carb. It will need a kit to freshen up the gaskets and pump seal. I cannot find a list # and the tag has been removed. Marked GM. It is set up for a manual choke. The primaries measure 1.550 and the secondaries 1.675. It is an older rebuild or old stock carb that had not been used. The photos show its condition. Original plating still in very good condition. $150 + shipping I can ship ups, fedex, or uspo. Your choice. I will double box it so it will be a little heavier. About 7-10 lbs un boxed.
