Bill:
I think, respectfully, you may be off in your assumptions. I am looking at a PRC aluminum radiator set up. Now, I can go with either a clutch set up or have a dual Spal electric fan set up. The dilemma is that I need information prior to moving forward. Why ? If I order the PRC radiator and go with electrical fan set up, I can order the radiator made with an internal automatic trans cooler, and the Spal Electric fans will be attached to the radiator by PRC, along with built in shrouds. So, it will be a custom made set up. And, it will fit and work.
Now, I have had a PRC aluminum radiator made last summer for my 67 Chevelle SS. I went with a clutch fan set up since I wanted the 67 SS to have an original look since it is a numbers matching vehicle. I painted the rails radiator black to have it look original. The PRC radiator keeps the temps much lower. I kept the old radiator for resale if I ever sell the Chevelle.
In contrast, I am not concerned with the 67 Chevelle Malibu being original looking since it has a 383 stroker and other mods. So, I am asking inputs on whether a fan set up vs. clutch fan set up is the way to go.
My only question is on the set up. I have talked with others who advise that the electric fans will work at idle and kick off at cruise speeds when the temperature comes down. Therefore, the two electric fans would be working at idle and probably have enough CFMs to cool at idle.
I have already decided to upgrade the alternator to either 100 or 138 amps.
Again, I need other comments from Chevelle or other car owners who have gone with the electric fan set up. Are you happy or wish you did not go to this set up and stayed with the traditional clutch fan or flex fan/shroud set up.
Thanks again,
Ken McDee

Bill,Looking at the dual 11" Spal fan spec sheet and it has the overall width of the unit at 23.46" and the mounting holes are inside that dimension. Is there something missing from their tech drawings that would account for the extra 7.5" you mention?Dale McIntosh

Subject: Re: [Chevelle-List] Yet another question: Electric Fan set up versus Clutch Fan set upI'm going through this right now on my 67. Here's what I decided.A quality electric fan will not be outperformed by any mechanical fan at idle / low RPMs, and that's where we run into trouble, in my experience. The Spals are good units, but I don't think that dual 11" setup is going to work for you - you need a 31 inch radiator in order to mount it. I'm going with a single 16" puller, myself.You may need to upgrade electrical components. I intend to do so anyway, and am still researching...Enjoy,Bill----- Original Message -----From: Ken's EmailSent: Tuesday, January 28, 2003 8:32 AMSubject: [Chevelle-List] Yet another question: Electric Fan set up versus Clutch Fan set upRegarding my 67 Chevelle Malibu, I am deciding to upgrade the radiator to a crossflow aluminum radiator. I can also go with either the traditional clutch fan set up or have two spall 11 inch fans incorporated into the radiator (along with a built in trans cooler).
My question is what set up do you prefer, i.e., the clutch fan set up or the electric fan set up. And, have you noticed most modern cars have gone electric ?
Your opinions sought. Thanks,
