Cooling help?

FWIW.

I have several vehicles successfully running around with 7 blade viscous fans, NO shroud.

Can you get a measurement from the fan mount flange to the rad. It's gonna be close, but a OEM 69 clutch fan is 2 5/8 inches from flange to end of clutch, 3 1/2" for a moho 7 blade clutch that I commonly use..

and Yep, the fan clearance is only about a 1/4 inch from the clutch to the rad, the motor is secured from moving forward in case of abrupt stops.

After 4 yrs of spirited driving by my son,, no interference yet.. lol

I'm touching wood here.. lol
