440 68 barracuda radiator fan fitment

IMG_0392.JPG (2).jpeg
I have a cold case 18x22 radiator. With the 440 in the car, it leaves 2.5 inches between the face of the radiator and the water pump pulley. What fan would fit? would prefer to go electric.

What is the thickness of ur rad. ? Mine is a 28x19 / 1 1/4' tubes / 2 row , and I have a little more room than that. I only run a mech. 17" fan , but have my cooling problem whipped , after a lot of testing diff. set ups last year .
With a 17" fan, I cant run a clutch type fan because of the size of the clutch itself , blocks a little air flow, and what I got is critical w/ the little fan. Electric fans didn`t work for me but a lesser engine they probly would.
I have quite a few diff. fan set ups laying on the bench ,from a 2 5/8" new jaguar clutch fan , to a 15" elec , and a few in between.
Make sure ur rad. is up against the cradle to start with--------
