downside of a 26" radiator on a 22 support?

I have used set screws before as studs, they work good.

That would have been good to know. LOL

My Jag clutch and 216 fan are officially on the shelf. Went back to my Flex a lite flex fan yesterday. The standard duty clutch just wont cut it.
I did the swap and went for a drive. Ambient temp was 84 and engine temp never went over 180. It was 200+ with the Jag and 216.
Maybe my radiator is borderline? Maybe with a big aluminum one it would be fine?

I will keep this in mind. I know the clutch fans only run 70-90% of pulley speed. The heavier duty the fan clutch the higher the % according to Hayden. Sorry it didn't work out.

According to the Hayden site the standard duty's run at 60-70%. Heavy Duty's 70-90%, and severe duty's 80-90%.
No worries, it was a good learning experience on how fast a person can change out fans.
