I can't help with the water pump pulley, but I do run a 6 bladed fan and I don't find it noisy. The biggest improvement to cooling I made was having a bigger core put in the radiator. Mine looked in good condition, but when it was inspected it was found that only a third of it was working. Since I had it re-cored I never have to switch on my electric back up fan (which was also a great help when in a traffic queue). If your radiator is old and stock it would benefit your cooling having it upgraded.
i have had 2 57s that i installed the steel 6 blade fans on with no problem and they are quiet. the flex fans are very noisy
Did the 6 blade fan help cooling? Did you use a spacer?i have had 2 57s that i installed the steel 6 blade fans on with no problem and they are quiet. the flex fans are very noisy
6 blade helped and no i didn't ad a spacerDid the 6 blade fan help cooling? Did you use a spacer?
Thanks
No reason for a six-bladed fan to be noisy unless you don't tighten it down. Yes a six bladed fan will pull more air through the radiator although it only makes a difference when stopped or at slow speeds. the fan needs to be spaced such that the center plate of the fan is paralell to the edge of the shroud for best efficiency.. I cannot tell you about the the pulley or an aftermarket spacer with modified volute.
i was not talking about a regular steel 6 blade fan. the flex fans blades flex at speed make a fair amount of noise.No reason for a six-bladed fan to be noisy unless you don't tighten it down.

direct bolt on. i think i may have one out in the garageThe 6 bladed fan you guys are using, is it a direct bolt on like the original or a clutch fan ?
Thanks, Tom
I’v been running this spacer for the last 3 years, noticeable difference when engine is idling.Have you installed this spacer?

Chock one up for stupidity! It helps to install the fan on the right way!!! D'OH!!! LOL!Where did you get the longer fan spacer for the 6 blade fan? The stock 1.18" fan spacer is too short and 6 blade fan hits the crank pulley.
Interesting your fan looks bigger than mine and is farther back in the shroud. I used the stock 4 blade fan spacer.Mine came with the car when I bought it, but I believe its a standard bolt in. See pics attached.
