In the pic it looks like the fender/door body line is off - is it an optical illusion?

It’s an illusion, only thing that is off is the hood from where I took it off to put the engine and trans in.

Awesome that you got your temps under control with nothing more than a fan swap!

I saw in your other thread about LED dash lighting that the A/C installer messed up your dash somehow. What happened?

[64speed]

My gas gauge bounces now and the warning lights are all plugged into the wrong ports and some of the illumination sockets are just hanging. I gave them a schematic too

[64speed]

On to the next part. The seat doesn’t latch on the passenger side and the lever doesn’t always unlock the drivers side. I ordered the spring kit from inline tube. Is this all I need?

Are you referring to the seat track to slide it back and forward? Or the seat back tilt? If the latter, you probably have fabric interfering with the latch mechanism- something the upholstery shop can resolve if you’re unable

[64speed]

I am referring to the track but it’s always been broken even when it had the only nasty seat covers on it. I think it just needs the springs.

so nice to have a car that doesnt overheat

Glad you got it figured out

Back about four or five pages ago I suggested that raising your idle could have a dramatic affect. Just sayin...

Glad you got it under control!

Where have you sourced these RV nylon fans? My Lemans needs a reverse rotation from the stock clutch fan and those might work very well.

Flex a lite makes them, most any speed equipment company sells them.

Pricing varies a lot, they used to be under $20, but nowadays who knows what a company wants to mark them up to.

I've been using them since the late 70s for race cars, as well as street cars.

Sirrotica, are you implying those fans move more air than a 19" 7 blades clutch fan assembly?

At that time raising the idle even to 1200 did nothing

If you look at the pitch of the fan blades you can draw your own conclusion. I know that I've never had any OH problems that could be attributed to inadequate air flow since I started using them, street or race cars.

If you use a smoke test in front of the fan you can see the volume of air they move. One other thing is 11 ounces hanging on the front of the waterpump is much less than any clutch fan.

They are specifically designed to move more air at low RPMs, and they move a ton of it.

[ZeGermanHam]

The plastic flex fans may move air, but they come with a massive cost. Engine Masters (season 2, episode 20) demonstrated that the plastic flex fans are among the absolute worst options in terms of power loss. When run to about 5500rpm, it killed 24hp and 19ft-lbs. In comparison, a stock clutch fan killed 14hp and 7ft-lbs.

If you can keep the engine sufficiently cool with a stock clutch fan, that is the best way to go. The only fan type that killed more power than the plastic flex fan was a stock style fixed metal fan, which killed 30hp and 19ft-lbs.

[64speed]

So far so good. With the heat index of 101 today the temp gun said it was 197 and the gauge was hanging between 195 and 200 so I guess its accurate. I didnt idle and hour or anything but I ran a bunch of errands and then came home and let it idle about 10 minutes. Driving down the road its straight 180. I am not kidding, for some reason all the other fans were low volume, even without the clutch engaged if you stand on the drivers side it will blow your hat off practically.

If you can't drive the car because it overheats, what difference does 10 HP make?

My first use was on my dirt car. I had overheated the engine and destroyed it, about $3000 dollars in 1977 money. I'll forego the HP savings (10 HP difference, over the coveted clutch fan at 5000 RPM) for reliability.

I never said it wasn't going to cost HP, I said it cooled my problematic engines. I never was worried about the power because if you can't finish a race what good is 10 HP? I'll bet money that no one is running their street engine at 5000 RPM all the time, as they did in the dyno test, so at reasonable street RPM, the loss is going to be a lot less.

Freiburger said the blades were supposed to flatten out at high RPM, I never took that it was in the design parameters to save power. IT MOVES A LOT OF AIR, and it doesn't overheat, that's all that I cared about. If you need 10 more HP in your street machine at 5000 RPM don't use a nylon fan, simple. If your car is overheating, and you can't drive it, maybe consider a nylon fan.

Their conclusion was to use electric fans to save HP, but of most of the people that have tried that on a Stratostreak V8, haven't pulled it off, many more failures, than success stories. It seems to work on a SBC, but we aren't running SBCs.

[ZeGermanHam]

My view on the plastic flex fans is that they are a last resort type of scenario, and usually aren't necessary. Agree that power savings aren't worth anything if you can't drive the car, but in Dave's case, his overheating appears to have been cured with an appropriately sized clutch fan.
