    Well I never would've believed it but after watching engine masters, the Dyno results showed that Stock GM 6 blade metal fan took 30 hp to turn on a SBC 350. (Check out the episode on YouTube). Not here to talk about that but I am interested in feedback on electric fans. I built my 81 Z28 motor to. 383 stroker w alum heads, etc etc. I put an aluminum Champion brand 3 row radiator in it (cools up to 750hp or something obscene like that). My car never runs over 185 degrees now.

    Well now I want electric fans. Probably dual? Any info on CFM and more importantly how are you guys mounting them?? This has been an area of interest because I've seen anything from zip ties thru the radiator to custom aluminum brackets aftermarket. Also then will I need stronger alternator?

    Any help is much appreciated guys!

    Take a look at the 4th gen Camaro dual fan set up. They can be had for a good price at junkyards most of the time and fit our cars extremely well. The shroud they come in will slide in to the bottom of the core support and at the top the factory cover over the top of the radiator holds it in place. If I recall I might of done a tiny bit of trimming on the shroud but I believe it still fit without it. I would recommend upgrading the alternator but there are a few good threads for that if you search the site.

    I'm running a two speed mid-90's Ford Taurus fan. Cheap as dirt on ebay and they move a ridiculous amount of air.

    On my website, I have short write up on how to install it.

    You might of opened up a can of worms about the mech. fan but I'm with the electric fan crowd. I'm using the big single, 2 speed Thunderbird fan. Another junk yard find. Had it for 4 yrs now, works well in this Texas heat.

    Plenty of good options from the wrecking yards. Take a gander at the topic *How much power does a mechanical fan eat* in this section.

    I'd suggest upgrading the alternator before the fan so there's no surprises.

    I have a nice dual fan set up from a newer impala that fit right in I had to do very minimal trimming and it looks/ works great. Another member scored us both one for $20ea at a local junkyard, we both upgraded alternators as well 150 amp
