Fan options

[OldChevy61]

Looking for electric fan options for my 62. 350 SB, 4 speed, 3 row champion aluminum radiator. New or pick n pull.

Go with the Lincoln Mark VIII or the Mercury Cougar XR-7 fan. They really do the job well.

I've had good luck with a dual fan with shroud from a 2006 Saturn Vue.

Is there a particular reason why you want to go electric?

Here's my take on fans: A good 7 blade clutch fan and a stock shroud will vastly outperform an electric fan. I live in the desert of Southern California at 3000ft of altitude where it gets over 100 degrees in the summer for weeks on end, and all I use are clutch fans and have never had overheating issues, even on small block 400s.

I see a lot of guys shun the factory stuff and go electric because they have an engine that runs hot and the first place they look at is the fan. Usually that's not the culprit! It's TIMING. An engine with too little initial timing will run hot because the burn is happening early and causing the engine to heat soak. Keep your initial timing between 12-16 degrees, with total of 34-36 degrees. You will be amazed at cool the engine runs.

Just food for thought. If you're going electric because you're crunched for space, I totally understand. There are some times when a clutch fan and a shroud just aren't an option because the engine is so close to the radiator.

I'm not set on electric and after reading on all the wiring ,switches,relays ,etc, I will most likely go with the clutch fan..

I think it's your best option if you want simplicity and functionality. The factory stuff works really well.

That's where I'm going with mine.

I used a Spal fan. So-Cal said it was the best brand on the market for electric. its loud turns 2,370 rpm but rarely turns on.

A simple trick to hep out a mechanical fan is to seal the shroud to the radiator. In my case an old rear window seal fit perfectly. I just pressed the the shroud into the channel.
