I am considering switching from the stock 5-blade fan on my 351W (basically a stock '70 motor) to an electric fan. I would like the added HP, but more importantly the improved cooling. I have integral A/C in my car and live in Houston which, temperature wise, is like living in Satan's backyard. Any suggestions on what size or what brands work best? I have the stock 3-row, 24" radiator and drive my car frequently.------------------

Flex-a-lite Black Magic. Comes with integrated relay and automatic temp-controlled adjustable switch. Also comes with shroud that fits old Ford radiators almost perfectly. I have one. Its the third and last electric fan I've bought. 5 stars.

Thanks cpmaverick and Richard. I looked at their web-site and really like the looks of their product.

My favorite electric fan feature is that I can run them when the engine is stopped, which cools the water in the radiator big time before you restart it.------------------

JT,
You might consider the flex-a-lite dual 12" fan I have on auciton at ebay. $50 less than Summit/Jegs.http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=584894483 Regards,

I couldn't keep my car cool regardless of what I tried. I first went with a 3 core and then a 4 core and it would still overheat. I finally modified the compartment to accept a 3 core SVO cross flow and I installed 2 Summit high flow electric fans. Finally my car would stay cool except if in in stop and go traffic for too long. My motor ran great so I was never really sure why it was running so hot. I'm hoping with the new motor being built now all my troubles will be solved. If it still gets hot I'll be switching to an aluminum radiator and the black magic fan.I wired my fans so they were temperature controlled but I also added a switch that allowed me to turn them on anytime I wanted. This is a nice feature to have. ------------------

Just be sure to measure your water pump to radiator clearance before ordering a fan. A Black Magic fan would NOT fit on my car. I had to go with a thinner one. Measure before ordering! Good Luck! ------------------

As far as radiators are concerned, Griffen universal ALUMINUM models are available from Summit and Jegs for around $180. These have two rows of one inch tubes (about the same thickness of a 4-core).These are crossflow units built for the circle track crowd, but work great in muscle cars. You purchase them by their dimensions, and inlet/outlet location. Some minor fangling is usually required, but a lot of money can be saved... The "chevy" radiators have the inlet/outlet in the typical "chevy" locations, the Ford radiators have them reversed. I believe the Chevy locations are (looking at the radiator from the engine) top on the left, bottom on the right. Ford, top on the right, bottom on the left. Do a little measuring, a little fangling, and save some bucks while helping your car run cool.  I've had a few buddies do this swap with good success... a couple chevy guys, and a couple fords. All cool really well. Good Luck! ------------------

I installed the flex-a-lite 210 package last year and it was a perfect fit on my 69 Cougar with a 26" 3-core newly rebuilt rad. Fan package covered the rad almost perfect except for a 1" strip down one side which I put a strip of steel over. It seems to cool my relativley stock 351-4V OK but am still having problems in stop and go driving. Thinking of putting a external tranny cooler to cool the C6 with 2500 stall and thus, hopefully, lighten the loading on the rad cooling more. I like the adjustable temp control on the fan package, stock 60A alternator is keeping up OK with lights on and stop and go traffic. Voltage comes down to around 10.5V when stopped at a light at night, daytime running is OK (11.5 V is typical low limit). I think the fans are doing all that I can expect them to and more than a belt drive fan, I just need to look at a few more things such as keeping the voltage up and putting the tranny cooler on its own. May have other issues that are affecting my cooling and am still going one step at a time. Ken

Thanks for all the advice. I'm leaning towards the Black Magic. I think the 210 is a little too wide for my application. I think I have just enough clearance for the Black Magic.

N20 Mike, how beefed up where the guys motors that installed those $180 units? I am looking for something to replace the stock unit in my 351C that is getting some MAJOR mods right now and that is in my price range...Do you think they will provide the cooling capacity of a steel 4 core? Also, If I were to go this route, I am assuming that they do not provide inlets/outlets for an auto trans? If not, is there anything wrong with running a big external tranny cooler all by itself for the trans? I see people ask this all the time but everyone keeps saying to run it in series with the one in the radiator...Why is this? seems like it would be a better idea to get the fluids away from each other?

i believe the aluminum radiators in summits catalog have the option of a built in tranny
cooler. the reason you want to run the external trany cooler in series with the one in the radiator is you get a more consistant trans fuild temp that way. and the way you set it up is run the output from the trans to the external cooler then to the radiator cooler. otherwise the fluid might get too cold and then you have problems. then way to tell which line leaves the tranny is to start the car (cold) put the trans in gear and rev the motor (not hard) against the brakes for about ten seconds. the warmer line is the one leaving the tranny.

One guy installed his in a Fox mustang running a 426ci stroker Windsor. The other guys were chevy boys. These are GOOD radiators, and cool exceptionally well. They have two one inch cores and are about the same thickness as a 4-core copper/brass unit. They are said to cool as well as a 5-core conventional radiator. They also sell a universal radiator with 1 1/4" tubes. It's around $265, but is overkill. I suspect airflow through a radiator that thick might be a problem. Everyone I know uses the $180 unit. Go to...

for more details. These are part of their "Nascar" line. As for auto tranny lines... I kind of doubt it on these. I'd just run a big cooler. You don't need the stock tranny cooler. Good Luck! ------------------
