Well, remember that all those recommendations are just that. But a difference of 250 may make a difference. Remember in the "OLD DAYS" when we would replace the clutch fan with a multi blade or a flex fan and never even worry about cfm ratings? Oh well, this one is a jump call for you unless someone has had some specific experience in this matter. I mounted a puller from a little Hyundai car and used a 180* switch on my '69 Delta with a 455 engine and it seemed to do well. My water temperature gauge would always go up to 210* but I think that was more of a problem with the gauge as the car didn't behave abnormally and the fan would stop running within a couple of minutes after I stopped the car so go figure. Use what you can get.
