Yes you can post them. FWIW, this setup is on a 390 with a 671 blower, so far I've had zero heating issues with her, but I have not run her during the summer yet.

Yeah, I didn't think to post the controller I also got for them. It's a thermo controller with a temp sensor mounted into the radiator that is supposed to be designed for dual fans.

My radiator is original to the car. But we did re-core it with a larger high performance core, removed the surge tank, and am using a more typical overflow tank on the fender.

I used the Hayden one for dual fans, #3654. I think I paid just under $50 for it on Amazon.

Here's a link to my photos of ole "BigBird" as my kids call her...

For the fan mounts I used flat stock with a bolt welded to it through a hole I drilled. Smoothed the backside so it wouldn't damage the vanes.

Opps, forgot to mention, I am running an aftermarket alum water pump, no surge tank and yes, I had the hood off while I was replacing it all. Never thought about the hood being an issue, sorry.

And I'm running a two groove pulley.

I love this setup:



After taking the old fan and spacer off there is plenty of room for a fan. Notice the foam between radiator and fan shroud. I also love that the fan controller is mounted in the lower corner of the radiator. It's a mistake to put it high, in case the water level in your radiator drops.

The fan cools the radiator. Engine temp has nothing to do with the fan. In Michigan winters, my cooling fan goes months without turning on. - Dave
