7 Blade Fixed Radiator Fan.

Just like this one, it appears to be 1960's vintage.

Anyone got? They are about $80+ shipped on eBay,

I'm guessing Diplomat_Wagon probably wants it for his race car, but on the street I'd much rather have a fan with a thermal clutch. It can disengage when not needed, saving horsepower and fuel.

If you can't find one, Dipster, Hayden makes a 6-blade flex fan that looks OEM. Rattle-can that sucker black and you're good to go... it'll save you some power, too. Those solid-mount OEM fans do not flex at all, and weigh a ton.
 
The fan doesn't have to be a factory piece. If it keeps the car cool it's legal. That's why we allow aluminum radiators and homebuilt shrouds. If there is something out there that's better I'm very interested. The only thing out here the speed shops sell are those shit plastic ones.

I would prefer to go with a solid fixed bladed fan as the OEM flex fans will not do the job. Even a 4 blade fixed is not enough on a hot day.

This is what you're seeking. The Hayden part number is 3568 and it has much larger blades than those spiky-lookin' suckers you see on hot rods:

I would bet one of your local parts stores could get it, if they don't stock it already. At Auto Value/Bumper-to-Bumper stores, it's sold under the PartsMaster name but I assure you it's a Hayden, as are their fan clutches. We stocked both this one and the reverse-rotation version for vehicles with serpentine belts.
 
Mine actually has light blades that kind of straighten out at higher rpm and curve back into shape to draw more air at idle.
 
Yeah... that's a flex fan. What you've got isn't factory, as far as I know. I've never seen one. When the solid-mount (non-clutch) fan in my '73 Charger let go, it shook the car so badly interior screws were falling out; that's how heavy the blades are on OEM fans. It wasn't original to the car, but it was exactly what DW had posted. The blade that broke was heavy enough to poke a hole in my inner fender, bounce across the engine bay hitting the hood on the way, and bounce back to land on the intake manifold next to the throttle linkage. No way would a flex-fan blade have that kind of momentum.
 
I picked it up off a Dodge something or other a while back as the thermal clutch fan I had was too close to the rad for my liking.
 
Why? That was the whole point... I told you originally it was a flex fan. Straight-blade fans are a huge draw at speed, and at speed you don't need 'em because you have sufficient flow across the radiator and the fan can relax a little.

Read my post again with what happened with a fan like what you posted originally. The newest one is 40+ years old; that incident happened in 1992. I was not racing nor was I at high RPM... in fact, I was parked and a cop that liked my car wanted to hear the exhaust, so I revved it a couple of times for him, maybe 4 grand. The blade came off, and it's a good thing I only had to go about a mile to get it home. Does the phrase "metal fatigue" ring a bell?

That Hayden fan is not a $20 piece of shit aluminum unit. I will not steer you down the wrong road, man. It's a steel center frame with stainless-steel blades. It's built like a brick brick because it's designed to be an OEM-type replacement for a clutch fan for cars stuck in Chicago traffic or on I285 in Atlanta, not a race-car part. It has to be reliable in all situations. Find one and put your hands on it. Love it and hug it and call it "George". You will not be disappointed, and you will likely buy it.
 
I know what your getting at Jass but I've seen a couple of our street class cars overheat and the flex fans get tossed. One of them was a brand new Flex-A-Lite fan.

4 blade, flex fans and electric in any configuration does not work. There is only one flex fan at the track on race day now and that '87 5th ave 360 2bbl aluminum rad overheats.

I just don't want to take that chance, I would prefer to stick with what I know works.

I found these and I think I should price one out here, Summit lists them for $28.

This one has aluminum blades.

Anyone know what size of fan I need to fit a stock 26" rad with shroud? I think it's like 17.5" fan. :hmmm:

I'll bet they were all running the dime-store flex fans, too. The Hayden seems fine for the circle-burners around here.

I'm not surprised the 5th Ave overheats. Aluminum radiators are nowhere near as efficient as copper/brass at dissipating heat. Copper and brass both have far-higher thermal conductivity than aluminum, therefore they cool far better. The only way I'd run aluminum is if there was nothing else available.
 
I don't know what other flex fans they were running but I know a fixed fan works great and keeps the car cool all the time. The car will be at 60 mph and 5000rpm in short bursts every 5-10 seconds, flex fan will not work I'm telling you.

All the chevy guys say is to install an aluminum rad "Throw that pos copper rad out and get an aluminum one! You'll run cooler." I had never bothered to do the research.

I have a huge by large C-body copper rad out of my wagon that I could plop into that stock car.

The boss wants to put an aluminum rad in his car so I guess I'm gonna scab the old one. :D

the cbarge unit is what i would use....

and im WITH you on the solid fixed blade fans.....i swear by them myself


what you seek is a 440 motorhome part...i do belive.....ill dig around i "might" have one
 
It's a rigid blade fan just with aluminum blades instead of steel to save some weight.

Flex-a-lite makes more then just flex fans.
