I would go with S Blade Pattern pulling about 3000 CFM with a good shroud inplace... Depending on your weather

Where I live(115+) that is no where near overkill as a matter of fact that is just right for using the ac in that weather. Anywho GM's single fan for the camaro pulled about 1350 CFM according to a direct replacement that napa offers.. As I said before it all depends on your weather...Whats it like where you live?

Re: what cfm to use????

I live in southern IL

on my 69 c-10 I put a radiator and electric fan out of a 86 TA

it works great

I dont like the horsepower robbing clutch fan which also robs mpg

running the fan direct robs power also so i use a thermostat

I am out of electric fans and have been looking at ebay and wanted to make a more educated purchase

thank you
