I can’t fit a 19 inch fan in my shroud but thank you.

An 18" 7-blade should still move a LOT of air.

They move enough to cool 800hp 600 cube engines

Do you happen to know if this one will bolt to a Hayden severe duty clutch

They show it fitting GM vehicles from 1967 to 1979, so it would work with the replacement clutches (like the Hayden variety).

Good luck!

Factory shroud? I would think about getting a bigger shroud if possible.

I have the biggest shroud that will fit my core support and radiator

This is from m '64 GTO. I made a custom shroud. So it is possible to have a 19" fan.

I’ve used these fans in the past with good success. They’re heavier duty than most of the aftermarket stuff. You can usually find them in different diameters. HTH

Yeah I have a stock pile of those. They are gm units with a part number.

Probably the best working fan on the planet, they pull a ton of air. Also great when you don't have room for a clutch

I stopped using them however when I started searching for HP, they are big hp suckers. I switched to clutch fans on the cars that I could. I still run 2 of those on cars with no room for a clutch.

Your fabrication skills are much better than mine but if its not too expensive I would be willing to pay you to build me one

One source....

"A fan shroud should fit the radiator, and there should be some clearance between the two. The shroud should be measured to the radiator to determine the correct size.
At least 1 inch of clearance between the fan shroud and the radiator."

Well, maybe not. I've done two conversions on friends' cars where we used the 19.5" fan and the big shroud on 15-1/2" radiators. Just takes making a hole through the large shroud for the bottom radiator hose.

The shroud bolts up to and locates on the radiator support so it remains centered with the fan. The top of both the short and long cores is in the same place so the only difference is at the very bottom.

It's been awhile but believe this shroud was from OPGI and the Ames shroud fits better up to the radiator.
