I installed the 7 blade fan I got from fellow lister Gary W. and finally got a chance to try it out yesterday. The temps were in the mid to low 80's and there is a definite improvement. The temp still creeps up a little like before when you come into town after highway driving and have to idle at a stop light etc. But not nearly as high. And bring the idle rpm up to 1500 and it will even start to creep down.
So to recap what I have done regarding this issue. I first installed a higher flow water pump, no help. I then installed an aluminum radiator, a tiny bit of help. And now the 7 blade fan. If the day wasn't too hot I might even be able to drive it in a parade. I'm sure a shroud would be the final piece of the puzzle. And I may spring for that some day.
Thanks Again to Gary W.

I sent you a text message with my address. And, no I don't need the spacer etc.
Thanks Again, Paul

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.
