I would like to get rid of my fan. I found a flex-a-lite 16" electric fan that puts out 2500 cfm 17amp. I will use as a pusher for now might move the radiator to 6 location later and use as a puller. Will this be enough fan? I have a 350 with 312 rwhp and no AC. I have a 17" flex fan and it does ok with no real trafic cant stay at a light to long or it gets to 200. How much CFM do you think a pully fan puts out. What would you do? Thanks

I have a 16 inch Summit fan mounted as a pusher in my car, but I also have a 16 inch engine driven fan mounted on a factory type clutch. My radiator is mouned in the 6 cylinder position so I have lots of room to work with. I do not know what the CFM of a factory fan is. I am considering doing as you want to, but if I do it, I will try to mount the elecric as a puller and try to incorporate it with my plastic fan shroud. Puller fans are more effecient than pushers. I would reccomend moving the radiator to the 6 cylinder postion. They only way to know is to try it and see if it works. In reality, you only need a fan when you are moving slowly. Once he car is moving, say 35 to 40, there should be enough air to cool the radiator. BTW, my car also has air conditioning and I have the electric fan wired to come on when the compressor kicks in. Lots of guys on Chevy Talk claim they only have an electric puller fan and say titworks fine. Good luck.

I had a problem. It keeps the radiator cool but with so little air flow in the bay my carb and pump got so hot it boiled the gas and it would not run. I put the fan back on and no problem. Now with the radiator coved buy the fan it runs about 184-188 at 70mph. In trafic goes back to 180. I fixed one problem and created a new one.
