Fan shroud for my 56

[samdjr74]

Hi All,

I finally found a couple of fans that will fit and move enough air to keep my engine cool. But I need to build a shroud to make sure everything stays cool. I have a couple questions and maybe someone can help me out.

1. The shroud will be flat, how far off of the core should it be?
2. What’s the best material to use for the shroud, steel or aluminum?
3. Should I put a seal on the shroud where it meets the radiator, if so what should it be made out of?
4. I have a probe temp sensor, should I run that through the shroud then fins or just the fins?

Thanks,
Sam
