It is an older one, maybe the new ones don't have this.

I had a 32 back in the 50's, and I opted for the Edelbrock 3-pot, rather than the Super simply because it had a mounting pad for the fan. I had to build my own fan drive, using generator parts, and a Fafner Flangette bearing assembly, but at least I had a place to put it. The 2-pot "street friendly" manifolds were kind of a joke, as they stuffed the carb bases way out of line with the intake ports. The "Super" placed the carbs where the needed to be, and nothing else mattered. Since the only issue is the fan, and since that issue is so easy to solve with modern electric's, I'll say that Ole made a great choice.

He really only has two choices: either run without a fan, or use an electric fan. If he had a 39 Deluxe, or 40 Ford, the choice of an Edelbrock Super would have only required a bracket for the generator that bolts to the head. Alas, he doesn't have that option. The upside, is that he has the best 2-pot flathead manifold ever created. Vic Sr./Bobby Meeks designed the manifold for serious racing applications, and they succeeded in that, but they created a problem for anyone with a 32-38/39std, or anyone with a 41-53 non racing application that required a place to mount a fan. 37RAGTOPMAN 03-09-2011 @ 3:30 PM reply profile send p.m. Senior Posts: 1959 Joined: Oct 2009 ole-bill CERTIFIED AUTO ELECTRIC in OHIO ,sold me a 6 volt alt, it came with a adapter to use the original FORD fan on my 1937 85 HP, it took 20 minutes to install,and was about $220. they advertise in the EARLY FORD V8 TIMES, It all bolted right on, and works perfect, if you have alt on top of the intake, you could get the adapter and use you original fan, this might solve you problem. my 3 cents worth, hope this helps,. 37 RAGTOPMAN and KEEP on FORDIN,,,!!!! 1933 03-07-2011 @ 4:06 PM reply profile send p.m. Member Posts: 25 Joined: Oct 2009 Sorry about that, I thought you were dealing with a stock 36 motor. Alan supereal 03-05-2011 @ 12:31 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Remember that 20 amps at 6 volts is only 120 watts. Most heater motors draw at least 10-15 amps. Many 16 inch fans moving about 2400 cfm draw 15 to 22 amps at 12 volts. That translates to 180 and 265 watts. With 6 volts, it means 30 to 44 amps. That is why the relay is required. There is another consideration. Most fan motors are permanent magnet type, and act as generators when air current rises enough to make them "windmill". Good quality fan controls are designed to eliminate these system "spikes". As with many things, installing an electric fan is not as simple as one might think. If you insert the sensor in a hose, it goes into one of the top hoses, as these carry the hottest coolant, and are closest to the radiator top tank.

Electric fans are rated by CFM and the amperage.The more of both the better. Most good electric fans also need a relay because of the amperage draw. supereal 03-05-2011 @ 10:10 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Any electric radiator fan that draws less than 20-25 amps at six volts is unlikely to be strong enough to replace the stock fan.
