Save it for judging and run an aluminum one for everyday.

Your title says steel, I thought they were aluminum? Be sure to buy a new one from a reputable supplier, some of the earlier ones had problems.

Aluminum ones are reproductions. The one in the photo is steel.

Did Ford make the cast steel fan? I have one,I just thought it was something aftermarket from the 30's,40's,50's,etc.I bead blasted it and used it.It IS a cast unit,not like the late 31 single layer fan.No seam in the back.It is very thin compared to the aluminum fans,but thicker than the original 31 single layer fan.I am running it on my truck,with what I call a tubular water pump.No packing nut,fully enclosed for the whole length of it with one grease fitting in the middle.

Model A Ford Garage comparison of A and B blades. They say the four blade eventually was the replacement for both. They didn't talk about a cast version so it must be something really odd.

As mentioned in post 8:

http://www.fordgarage.com/pages/twobladedfans.htm



Paragraph 3 of Vince's webpage as mentioned above:


1. The Model A fan was very prone to cracking


2. was replaced with an improved construction Model B style.



3. The Model B fan was also known as the Holley design fan.



Paragraph 4:

Version 2. At a glance it looks like every other fan, but it is a much improved construction, and was Ford's fix to the fan cracking problem which was becoming apparent at that point in time. These improved Model B fan blades are made from a single piece steel stamping.


Comment: This second version of stamped steel fan might be the one that is called "cast"?
