Still chasing cooler running temps. Everything tells me my problem is air flow. I'm running a 4 blade fan which I'd like to replace with a 7 blade or a clutch-fan. Before I make a trip to the U-Pull-It yard can anyone tell me what will fit as far as bolt pattern? I've got a fairly tight space with only 3 1/8" between the face of the water pump pulley and the radiator and 5/8" between the fan and the radiator. I am running a 1" spacer which can be eliminated with the use of a clutch-fan. This is all on a stock 440 w/ C.I. water pump.
Thanks, Paul L.
