Guys im switching out for a carb and i was going to use my serp belt system just get the delete pullys any way i was going to put a flex lite fan on the water pump instead of using my electric fan do i need a shroud for the fan or not? and will it make a difference in cooling temp?

What the purpose for this fan setup? What are you trying to do bro?

I dont want to use my electric fan anymore so i was going with a flex lite fan and use a 4 inch spacer and slap it on the water pump pulley. I am changing my car to carb and gettin rid of all the smog stuff so i was looking at another way to keep the car cool besides using a electric fan. I am using the serp belt set up and using delete pulleys for my ac and air pump so i was wondering about using a old school fan set up.

I know this isn't what you wanted to hear, but why the hell would you want to do that? Belt driven fans are outdated, old school, hurt power, hurt mileage, and flat out don't work as well. Even the stock single electric fans like the one I have and the one you probably have are better. There's a reason GM as well as every other car maker in existence switched to electric fans back in the 80s and never looked back.

LOL i just want to go simple.

Like darkshot said, im not trying to hurt your feelings or anything like that but you should just keep what you got (electric fan) because it looks WAY better and is WAY more efficient that with a belt driven fan. plus i doubt they mad a fan shroud for our car. Im pretty sure you can make one but good luck with that

just stay with what you got and use the money for something else dude.

If i remove the ecm computer the electric fan wont work right? that is why i was going to go with the old set up. I couldnt find anything about this posted so thats why i asked.

You can buy a stand alone fan controller for about 40$ just go to Kregin or AutoZone, it wires in and you can turn on and off the fans at whatever temp you want. That is what I am running; fans turn on at 180, and off at 160. Works great and is cheap, takes bout 30-45 min to wire in.

Just make sure you get the better one that is rated at 20 amps, and has a ajustable temp switch.

The single-fan TBI setup is controlled by the fan switch in the passenger side head. The computer has nothing to do with it.

ECM has absolutely nothing to do with the TBI based single electric fan setup.

And by the way - you said you want to "go simple". It doesn't get any more "simple" than leaving your setup just the way it is.

yea dude keep electric, you could make it real easy by just togling the fans take the power wire the batery ground it off and put the toggle in the car there ya go turn the fans on turn the car on and it will keep the at like 190 i did that to my car and it works just fine. keep her simple bro

yeah thats so true just go buy a hyper~tech cooling fan switch..to replace your stock one. runs much cooler. thats what i did...good luck

Also you won't be able to smog your car with a carb on it.

I am actually Kahless' neighbor and am helping largely with this project. I would like to use one of those stand alone temperature switches for his fans, however i cannot find them in my local part store. If you guys have a part number for either Kragen or maybe even Summit Racing that would help a lot. Thank you. Oh, and the smog thing, in the county we live in up here they only require smog when you first purchase or sell a vehicle. Once you pass the inital, you are good to go.

Nevermind guys, I found the thermostatic switches, thanks for the idea.
