I've got a Griffen down flow radiator with their fan shroud and Spal 16 inch puller fan rated at 1300 CFM I believe. They swear that setup will cool my '55 in 100 degree temps, with the A/C on, sitting in traffic. If I can ever get that car done, I'll let you know if it works or not.

You are welcome.
A later model stock type clutch fan has more efficient blades for moving air than a flex fan does. Flex fan blades are designed to flex and since fixed blades don't have to do that they can be designed better to flow air.
Also, flex fans can fail and be dangerous. Many reports of that happening out there.

Clutches vary for air flow performance vs drag depending on the application. Since your car has A/C, I would look for a clutch intended for a truck. It will maintain a higher percentage of the pulley speed than a lower duty version.

Wow! Thanks again! I have some reading to do.

Hi Roger. Do you have a specific model you would recommend? My radiator is stock but mounted in the middle of the cut core support-(not by me). I have a little more room behind the radiator than the V8 position, but not a lot more.

I used this fan behind a stock radiator mounted in the 6 cylinder position
dual fan SPAL 30102052 it tucks in the core support and I used 2 pieces of 1" aluminum angle across the inside of the core support "U" to make the bottom and top mounts.
be aware this fan makes significant noise when running.

Regards, Robert

Does Spal or the other manufacturers offer a "Slim line" fan for those of us with VERY limited space?..... or are they all about 3 to 4 inches thick? My choice would be a puller fan but I may only be able to go with a pusher unless there is a slim version.

My Rad Core Support is being replaced with a cross flow rad and support combo, but my fear is that if I can't make it fit with the stock core support, it may not fit with the PRC unit.

OP'r... sorry didn't mean to hijack....

Well Gil, two things can't occupy the same space, so something has to give. What's more important to you, keeping your engine cool, or keeping that 2" wide cog belt setup that looks cool? Forget using slim line fans, they don't move enough air to be used as primary cooling fans, except maybe if you live in Alaska. Pusher fans are only 80% as efficient as pullers and therefore not a good choice for primary cooling fans. Your only other choice is to install an HRD recessed firewall and set the engine and trans back a good 3 + inches.

Thanks Bitchin-

I didn't think that the slim fans would not more as much air, but your right... I need to get the full size fan in there.... I just can't quite give up my cool belt setup yet. I may try a pusher fan first.... thats probably the cheapest idea, before new motor mount location, trans mount location, firewall, shortened drive shaft.... maybe I will just relocate the radiator someplace else... like the roof.... Hey, why do you have a radiator on your roof..... let me show you my cool belt setup......:sign0020::sign0020:

So far so good

I'm running an aluminum 'stock' look radiator in the 6cyl spot with a 96 F*#d Taurus fan and shroud. It just fits between my SBC and keeps it at 190deg no probs. Unfortunately it draws about 70A and needs a heavy duty relay. All in rad, fan, relay, cost me $350 total. See other posts here that cover it all. Good luck!
