Fan Shroud help

I found a shroud for my 65 on ebay. Apparently it came off a 66 skylark.

It fits well and probably would be perfect if the original 300 was still there. In its place is a sbc, and you can see there is a fan spacer there too. The fan hits at the bottom of the shroud. I'd like to do as little modification as necessary to get this to work.

 

It appears that the fan will project too far into the shroud which will hurt its ability to cool.

 

1) Who put that stupid engine in the car.
2) Why is it sitting at such a sharp angle to the shroud? it doesn't look like it is sitting properly.

 

Well, you have a custom combination there so the fix is going to be custom as well.
There were 2 different radiator supports used in 1965, one for a downflow radiator, and one for a crossflow radiator. The lower portion is different between the two, I don't know if there is a height difference.
You don't have many options:
- raise the engine
- lower the bottom radiator support
- modify the shroud
- use a smaller diameter fan, or move it closer to the engine.

 

Walt: I decided on the 'move fan closer to engine'
Will update with finished photos.

 

Hoses and such have since been re-connected. Really nice to have a functioning shroud. Quieter, and doesn't allow oil droplets to be sprayed everywhere!

 

I'm with Jim on this one. Maybe use a shorter spacer, although it looks like doing so might put the fan into the alternator...

 

I was a bit worried about that too. But after driving and monitoring the temp gauge, all is well.

 

I believe that the ideal location of the fan blades relative to the opening of the fan shroud is approx. half of the blades sweep (as viewed from the side of the car) width inside the shroud leaving the other half outside the shroud.

From the first pic, it appears the fan is set up for a counter rotating engine - just making sure the fan matches the engine rotation for the fan drive ....

 

Good to hear!

 

Do I have the fan on backwards?

 

No, it's on right. I see you have the `69 & up water pump and accessories. I used the `64-`68 style with the short water pump and bracketry, mainly because I have factory a/c and wanted to keep the compressor on the passenger side. My alternator is on the driver's side.

 

Good. I went looking at photos. I'm not sure why the photo looked like it was anything other than a normal engine.

I read all about the fan blades' position within the shroud. But like I said I did drive it and the gauge actually didn't show anything different than unshrouded.

Plus, it would actually be a benefit if the engine ran closer to 200 than 180 from what I understand.
