Your link is dead. Can you send me your info on the fan and cooling issue? Email is (no email addresses allowed in public forums, take it to a private message) Running a '69 Formula S 340 and it runs hot! Everything with the car is OEM with the exception of the cam is from a '68 340 and Chrysler's vaunted electronic iginition. Pretty basic factory resto 340 4 spd.

I looked at what I've posted and that whole thread appears to have been deleted. Not sure why but that's for others to decide.

Let's try this... Here's a link to a thread where I show a pic and comment on the same issue of clearance. 440 A Body Cooling solutions? .
Look at post #19 I made. It has a pic showing the avatar's water pump nose and the fan assembly I use. Again, my comment/advice is that you can't use the overall thickness of the fan assy to decide if it will fit as the nose of the water pump does not line up to the thickest part (fan motor) of the fan assy.

I use a Champion Cooling Systems (NOT a Champion Radiator as this is a different company!) 22" alum rad. My fan assy is a Jeg's brand (made by Maradyne) that has its own shroud. Here's a pic of the fan assy installed to the rad prior to installation of the whole thing in the car.

After this pic, I installed small alum "angle iron" to close off the gaps on the side of the rad. You can also see the little flaps on the top and bottom that are supposed to open going down the road. Here's another shot of the installation.

I have plenty of clearance to the water pump snout - think its over an inch. This setup keeps the car cool in the Florida heat without issue. It runs in the 180-185 range going down the road in 90-100 ambient temps. If it starts to go above that, I flip on 1 fan and if still needed, the second one and the temps fall. At idle, 1 or 2 fans depending on the drive cycle coming to an idle but it will stabilize and run in the 170-ish range (2 fans) or 180-ish (1 fan).

At the track, it usually hits 185-190 at the end of the quarter mile (11.0x at close to 120 mph) and I flip both fans on. It is usually back to 160-165 when I get back to my pit.

Hope this helps!

p.s. This car runs an 8" torque converter as well. I do not route the trans fluid through the rad as it has its own separate cooler.
 
At least with this ^^ fan/shroud set up, it covers almost all of the rad core.
