Overheating on run stand

Thanks Dana, I think it was Karen not showing up... :lol: Truthfully I believe it was a combination of not anywhere near enough air flow(used Ridgid air mover this time) and putting fan blade on the proper way.
With blades on proper way it actually pulled the rad close to the fan. I heard it tick the shroud just above idle. Shut it down and shimmed the cradle to stop it flexing and getting sucked into fan at higher rpm.
**edit** timing too or lack of lol
So Steve...

What was the magic bullet to running proper?
