I've had this carb for a while now(model#4585), and was bought at a garage sale for 5.00, so i dont expect much. I have less than 250.00 into a project 82GT, and got a stock 4bbl aluminum intake for it recently, the carb fits, i just want to know the CFM numbers this carb has, i did a search and saw it probably came off of a 1968 289c.u. engine, Thanks
