We used to have a Badass Old School Carb shop here.. they were well known. Pinellas Carburetor... even though they were in Tampa. Not sure if get are still kicking. The 850 we had redone, for the 413 dart, cost 350 to get rebuilt, in 04, from United Speed World. I'd have never done that, they are crooked, for other reasons, but it wasn't my car..
