Our problem that small block guys don’t have it the lack of clearance between the water pump and radiator. It’s hard to find electric fans that move enough air and fit. I have a nice 18” electric that moves air like a hurricane but I can’t make it fit. Do some math a figure out a fan combo that covers the most area of the radiator and clears the pump. I’m running twin 11” fans,with the AC on it runs at 220 parked in traffic,last Saturday 97* here in San Antonio. Rolling at 45 the temp dropped to 195 in about 3 miles. No shroud. I ran a 6 blade solid fan, sounded like a turbine lost noticeable throttle response but temp parked on 190 with ac on . I tried a clutch fan,that honestly is the best set up , but finding the right clutch and fans and shroud can be a challenge. Something to remember is these cars where designed to drive in many conditions including very hot desert conditions ,tough to beat a heavy duty stock set up.
