Electric Fan...What size do I need?

[6781camaro]

Hey guys. I have a 1969 Camaro, 350 V8 zz4 Crate motor. I am looking to get rid of the flex fan and go with an electric fan set up instead. Can I use a single 16" electric fan, or do I need a dual 12" or 14" fan set up to cool the engine? I only drive the car to and from shows,and an occasional RIP around the block. Thanks for your opinions and help.

dual 11's would be fine...

You need to know how much air (in CFM) the fan will move to decide. I think you'll find that you need at least 1600 CFM for your engine. If the single fan can do that, you're all set.

taurus or mark VIII fan, they are great and flow 3400 or 4000 cfm are what alot of guys are using, round 100 bucks...

I appreciate the help! I found a new 14" "S" bladed fan on ebay for $27. It flows at least 2000 CFM's (per the ad info). I think this would do it. Let me know otherwise. Thanks again for the help everyone!

a zz4 engine is around 345 hp., look in a summit or jegs on the cfm needed to cool estimated hp engines. there is no way you can buy a new 4000 cfm fan for 100.00. i have a griffen 1.25 2 row aluminum radiator with a be cool (spal) chrome fan pulling 2360 cfm.. part #BCI 75033, available in black also. this is keeping over 500 hp cool on the street. and dont forget to purchase a electric fan relay kit w/ a thermostat. stay away from the crap on ebay. obviously it didnt work for guy whos selling it. ebay is the internet junk yard. you get what you pay for in this day and age...

the ford fans from a taurus or mark 5 are about $100--autozone
the taurus is about 3000-3400 cfm and the mark 5 is 4000 cfm

i didnt realise you were talking about ford fans. i couldnt find anything aftermarket that pulled that kind of CFM. so i retract my previous statement.
