I doubt the guys with electric fans that say they have no highway cooling problem take their cars on long trips.
i have a electric fan. i added the pace car spoiler and just cruise'n around town mine stays right on 180. on the hwy it drops to 170. and i have a 3.70 rear gear and run about 3800 rpm's at 70 mph.

That's what mine does.

160 t/stat it runs about that without the air on. With the air on it goes up to 190-200 on a 90o day.
If your car is running hot check all of the seals around the shroud and the support. These seals will make a big difference.

According to my gage, I am running under 160 in Houston weather.
It is reading between the first 100deg. mark and second line on the
gage, third line is 210deg.
guess I'll have to check it some day.
I am using one 16" electric puller,fan turns on every so often.
Guess I will have to stuff some cardboard in front of my radiator to
make it run warmer.

I have tried the electric fan route and in my experience they are worthless. The factory installed a heavy duty fan clutch that must create a negative pressure area behind the radiator to cool properly. The heavy duty fan clutch works harder than standard fan clutches at highway speeds. I doubt the guys with electric fans that say they have no highway cooling problem take their cars on long trips.

i can only go on my own experience. I put dual pusher fans on my radiator to aid in cooling and when turned on while on the highway they do squat to help. The guage doesn't even move. A stiffer fan clutch aids greatly in highway cooling. Better yet a locked up fan clutch works the best on really hot days.
Sorry if i seem to doubt, but i have put over 400K miles on my car over a 25 year period so i trust my own experience over the vast majority here that put a few hundred miles on their car per year, don't take their car on long trips and basically dive like their grandmother.

That's why spal doesn't even make a dual pusher! And their puller package has relief checks in the shroud to allow free flow at higher speeds.
You might have had a bad experience with dual "pushers" but I have hundreds of happy customers with dual "pullers".

i've tried puller fans before too. Less effective than the mech fan.
So you think it will make that big a difference if i mount the fans on the other side of the radiator?
As far as making air move the little 1/16 hp electric motors just aint gonna move the air a mechinal fan being driven by a 300 hp motor will.

I checked the temperature at the t-stat housing and at the neck on the radiator. the readings (per the infra-red thermometer) were around 170-180. My gage is reading around 220-230. My sending unit is in the head, between the number 1 and 3 cylinders, and acts as though it is getting transient heat from the exhaust, and causing the gage to read false readings. For example, I drove the car to work today (first time ever 
) and the faster I went (higher RPM's) the higher the temp went. When I was stuck in traffic basically idleing, the temp came down. All the seals are in place and brand new, and the motor only has about 50-100 miles since rebuild. Also, there is no t-stat in.

I think the thing you're missing with the mech vs. electric arguement is the fact machanical fans don't give you the air you need, when you need it. At idle and slow traffic, the mechanical fans are limited by the engine rpm, but with an electric fan you can have the air of going 60 mph when you're at a stop light.
Most cars don't even need an electric fan, if they are stock and everything is working right but will an electric fan provide more air at idle than a mechanical? Yes they will.

You did make sure to "burp" the coolant as you filled it, right? I leave the coolant sending units and stat out when filling the coolant. The first time I fired my 454 up NOT using this procedure I watched the plastic wire seperator melt before my eyes. An air pocket in the head can stay trapped a long time. My '73 454 with A/C (notoriously hot combination) runs around 190, however on a slow cruise night with lots of stoplights will keep my eye glued to temp guage, teakettle! What year is your car, I missed it if you stated it. (lot of replies!)
