The Hayden 2947 is the new HD version of the short 2765 Jag clutch which we all used.

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.
