4 Banger Single Electric Fan
My car has an early 70's Vette engine with a mechanical fan and it's missing the lower half of the fan shroud. It consistantly runs between 230 and 240, so I picked up a big single electric fan from a four banger Firebird. It'll bolt right in without modification, but will it be sufficient for my 9:1 350? I'm running a brand new stock replacement, single core, 5.0 aluminum radiator
I also picked up a fan switch from a 90's 1500. Should work.

Have you run a infrared thermostat on your radiator to see if you're actually running hot? Could be your gauge is off. I know for a fact mine reads about 20* hot compared to the fan switch turn on...

I would try an aftermarket gauge, otherwise it looks good to me. I am running the SW555 switch that comes on at 210F

I run a single fan in my 84 with a 350, 9.1 compression, 315hp and it runs fine. These cars were designed to run "hot", for emissions reasons.

Re: 4 Banger Single Electric Fan
I've got a stock RS L03 305 fan. I would bet money it's the exact same single fan in the other cars.... but the 4 banger was so many years earlier it may not be.
Either way, my 9.5:1 Vortec 350 runs nice and cool at 170F in the summer with all stock stuff except a stock replacement type 3 core radiator (or maybe 3 row? I forget).

Re: 4 Banger Single Electric Fan
I don't run any fan with my 2.8, long as the car is moving it never needs to run 180-190 steady. only at very long lights or drive thru's do I turn it on.
how
removed ac rad and use an aluminum air dam. most have chewed up or destroyed their air dam on curbs.
[ before that, 220-240 with fan running always]
aluminum wont chew up, just makes a great scrappin sound when you pull to far forward.

Re: 4 Banger Single Electric Fan
The angle doesn't really matter. It's a bit counterintuitive but it creates a negative pressure zone behind the airdam, which forces air to flow through the radiator to get there. Aluminum is cool, but one of hte things about using plastic is if you hit something HARD, the plastic breaks, not your frame.

Lol thats what i said! Aluminum vs steel, steel wins!
Then again, it depends on how thick the aluminum is...
I just used zip ties, if i hit something itll just break the zipties. Really helps cooling cause you can angle the stock airdam real far with the zipties.
