Electric Fans?

[hoser]

I just did a engine swap in my 72 GMC removed the gas hog 400 and installed a stock 350 in trying to improve the MPG a little, my dad had bought this truck used in 1978 and it came with a fiberglass flex fan was this factory? I would like to replace the flex fan with electric fans I figure they will also help with the MPG?


Can anybody recommend a brand or setup they have had experience with?

Thanks

The fiberglass fan is not factory. The electric fans will help MPG. I know somebody else in your area has got to have them available and maybe even cheaper (who knows), but there is a really awesome bolt on electric fan kit specifically for these trucks you can look at it on kennystrucks.com . I am sure that a company like ECE also has them available I think GMCPAULS has them to.

We have a nice selection of our own electric fan assemblies. They are not the cheapest on the market, but they are designed specificly for our trucks and come complete with all stainless hardware, switches, thermostat, and marine grade terminals.

I am a firm believer in the electric fans. Here's a link to a previous discussion about this. http://67-72chevytrucks.com/vboard/s...d.php?t=180910

my '77 had a metal fan. You can go to the junkyard and get a nice fan out of an 80-90s ford, there's a ton of the mout there, and go t oadvance auto parts and get the hayden relay/probe kit for about $27. I got a couple dual fans fro ma bonneville, and made custome brackets, but thought it was overkill, so got a single big fan that draws about 20 amps. (the others drew about 18-20 each). now have to fab up new brackets. The downside on dual fans with our older vehicles is we don't have a lot of electricity to spare. So you'll have to consider an alternator upgrade as well. Jegs has the chrome 1 wire 100 amp on sale $20 off, for 99.99 (555-10100), or if you wanna go cheap, the black one (555-10120) is 89.99. remember, these old alternators only put out 67-72 amps. just my .02

I run one of these on my truck and it works great, looks great. Everyting you need is in the kit. It has a nice small profile, and I need all the room I can get with a BB and long water pump setup.

Electric fans are fine, but all it takes is a bad wire or a relay going bad to render them useless. I have done many a head gasket job due to electric fans not kicking on...and not just on 150,000 mile old junk cars either...some fairly new ones too.
A fixed bladed fan on a fan clutch is hard to beat, esp if you plan on towing.

I couldn't agree with you more! A fixed blade fan is very cheap, reliable and effective. Sure a wire going bad will render an electric unit useless. There are an infinite number of parts that can fail that will shut us down. A water pump could fail and blow a head gasket. If we aren't aware of our surroundings, watching the gauges, listening for unusual sounds or smells anything can happen. My older brother drove off with a Camaro I used to own and ran it hot, blew the head gasket. I think there are people on this site everyday looking for help tracking down bad wires that have shut them down for one reason or another. Once again I am by no means disagreeing with you. I still know people that won't run HEI because they are afraid it will fail. I guess that's why this hobby is so great! We have different people with different ideas building their trucks. If I wanted to see trucks that were all stock and looked alike I would spend all my time looking at GM's site and their new trucks .
