My 83 /forums/images/graemlins/k5.gif w/ 350 has had the clutch fan replaced by 2 electric fans. I don't think that they are doing a good enough job. My engine gets hot sitting in traffic too easily. Anyway..I want to revert back to the stock fan and possibly keep the electric for supplamental(sp). Can someone please give me a measurement from the front of the fan to the radiator and from the pulley that attaches to the clutch to the front of the fan? Anyone that has a setup with both engine driven and electrical fans please post a pic to show me how you fit them.
