Im finding a lot of different options for pullys. 3/8, 7/16, and 1/2. If you balancer is 3/8" does that mean your committed to 3/8" on the rest, or can you mix and match? Is there a good source for replacement pullies in all widths? Are any of the pullies designed to accomodate more than one belt width? If I understand correctly, the proper placement for a belt in a pully is to ride high on the pully. In other words, not burried in the groove, but with a little bit of the belt surface riding just above the surface of the pully. Is that correct?

Darrell;That is my understanding too. If the belt bottoms out in the pulley it will slip and squeal. Best to try and have all the pulleys with the same groove width.Rono

Thanks Rono. As of now, I came across a good NOS double sheave balancer and installed it for future upgrade to power steering. It has the 3/8" grooves. I have a 3/8" water pump pully as well. That leaves the stock generator which has been changed over to a gm one wire, which I believe has a 3/8" groove as well. The all line up. Wondering if I should use one belt or try and figure out how to use two belts.

I might as well put my foot in my mouth. Im looking at the stock fan blade to see which way it should be installed. One side has the four rivets holding it together finished heads on one side and the tails on the other. There is a "ford in oval" stamped on the side with the rivet heads. Looking at the fan facing the engine, I believe it rotates clockwise. It appears, with emphasis on appears, the fan blows the cooling air back towards the engine regardless of which way the fan is mounted. Not quite grasping how thats possible, but so far, it does not look like it makes a difference. Were these fans designed so they can be mounted either way? Is there a right way and a wrong way the stock fan should be installed?

Most concerns about movement of air have to do with the circular rotation of the fan itself, not just the direction the blades are pointing. I believe the finished head side goes toward the radiator.

Thats what im more less seeing. When I compared the fan to an electric circulating air fan, its all out of sync. I guess if the purpose is to blow air towards the radiator to cool the fluid makes  more sense than blowing cooled air back over the engine makes more sense. I just never really thought about it. When your going down the highway at 60 mph with the air comming straight at you and the fan blowing it straight ahead, seems like the faster you go, the less effective the fan would be. Almost like they would be "fighting" each other.

Since we are in this area of discussion, let me ask this; What is the normal distance between the fan and radiator core? Rono

Here is what a dual drive belt setup looks like. The damper pulley is from a 63 truck, I think number is C3TE. I had to machine the rear surface of  the power steering pulley and the front surface of the dual sheave pulley total about 80 thou to allow bolting them together. I had Damper Doctor balance the complete unit. marv

Not sure on that one Rono cause I dont have any of them together yet.

Marv,  I see double pullys between the dampner, water pump, and alternator. I cant quite see the power steering pump, but it looks to be a singl pully between the dampner and power steering unit. Correct?
