    If I remember correctly the blades are set at those positions for noise reduction. Kind af like truck tires have the tread patterns designed asymetricly so they won't create such a howl. If you remember the old truck tires in the sixties were so loud you coudn't hear yourself think while driving next to them on the hiway. Of course the trucks were pretty noisy too.

        The offset fan blades are to keep the noise down. If the blades are at the same spacing and have the same width, you'll get a sound like a fire engine siren. Having the blades at irregular spacings spreads the sound over a wider frequency range so you get more like the whoosh of "white noise" than a shrill howl. It's tougher to design and balance, but easier on the nerves.

        As one of my high school teachers used to say as he handed back the test papers with grades ranging from F to C, "Gosh, physics is fun!"

            Thanks guys! Funny that Stude used some 6-blades as well that were symmetrical.

                I knew a club member back in Texas who had a six bladed fan for the viscous drive. Stated it was something Studebaker offered but very few were ever produced. He wanted to put it on his R2 Avanti to keep the Texas summer at arms length.

                I actually found an seven blade aluminum fan off a Dodge 318 that fit the Studebaker viscous drive. Put it on my old 62 Champ 7E7. It was pretty impressive. It would almost pull the dead grasshoppers through the core!

                    As for why the five blades, I can't say from experience that 5 blades make less noise, they seem plenty noisy to me. What I have noticed is that with 5 blades it is an awful lot easier to take the supercharger belt on and off and remove the fan itself. The big gap leaves a space to work the wrench.
