Anyone ever put dual cooling fans on a 3.4?

I was wondering how hard this would be to do on the Camaro in my sig.

I plan to do an LT1 swap down the road, so it will need to be done anyway eventually.

I wired in a set from an LS1 car on my 95. Fans sit in the same brackets your single fan does. Perfect fit. Very noticable difference in temps and effectiveness. I wired mine up with relays, one runs to the battery and my aftermarket temp sensor, the other is set up to kick them on with the factory feed wire-A/C on remote wire. I plan to wire in an override switch when I get some time, Will only be one more wire to run in to the switch and tap into my current relay. The dual LS1 fans do pull a chunk when they kick on, not really good for the alternator set up this way, but I can live with it. Im guessing the LS1 cars are somehow wired up for soft start or just a bigger alt. that can handle the amp draw at startup better.

I think the LS1s had a bigger alternator. I'm basically going to try to get it to work on the stock relays I have now. I think the V8 cars have an extra one though, not sure how that will work out.

Thanks for the info.
