Pusher or Puller ?

OK Guys... It's about time to put things together. '41 Coupe, 350 sbc, 700R4, '76 Camaro rearend. I'm sure I'm going to need more air to keep it cool. I considering a Zirco, but should I set it up as a Pusher or Puller ?
Going to run A/C at some point in time.

It's a Cruiser, basic hp. Any ideas or experience ? Don'tforget I'm still a Newbie

If you have the room you should do it as a puller. Especially if you are going to put a condenser in front of your radiator.
I never liked putting a fan in front of the radiator.

Mikey is right. Pullers are more efficient than pushers.

Pusher or Puller ?

Thanks guys, I was leaning that way but just didn't have the conviction.

I still like fixed blade mechanical fans myself....the more blades the better and with a proper fitting fan shroud.

A mechanical fan and a proper fitting fan shroud will out perform any electric fan hands down. Having said that, if you are set on an electric fan then the puller is the best route.

I have to agree with 302/z27 but if you do go with an electric look into a Ford/Lincon v8 electric fan, Someting like 90`s Lincoln Mark 8 if I rember right You can do a search on this site about them. They are suposed to pull A LOT more air than any aftermarket fan.

Pusher or Puller ?

Thanks for the responses guys. I guess the only reason that I was leaning to an electric fan was because of the shroud issue. I haven't dropped the engine in yet, so I'm not sure how much room I'll have.

The other issue is the radiator itself. I'm kinda on a budget right, which hotrodder isn't except Coddington,Foose etc. , and don't want to get involved with a costly radiator. The stock radiator probably won't be sufficient, although I have a friend with the same setup, '41 Chevy Coupe and he is using the stock radiator w/ an after market fan.

Because you do not yet have the engine in ...
I strongly suggest you go ahead and buy a GOOD aftermarket radiator.
Then you can install the engine where it fits BEST ... using a good radiator and a shroud.





Walker ( and others ) makes quality radiators and offers a shroud to fit them ... that YOU cut the hole where you need it ...



Here is one I installed on my 1932 Ford roadster.
As a Moderator of the General Rodding Tech area ... I cannot begin to tell you how many rodders ask " How to cool my Hot Rod ? " ... and already have their engine installed ... too high ... too far forward or have a cheap, inefficient radiator and try to use a electric fan ...

Having a Hot Rod that overheats and gives problems is NO FUN ... so go ahead and buy a decent radiator ... and eliminate that problem before it arises. My Walker is a 1988 ... and as served me well for almost 20 years. I just bought another Walker for my 1932 3W coupe project and YES ... they are not cheap ... but then again neither is buying or building another engine ... after you COOKED IT DOWN ... with the cheap radiator ...

Big Radiator + Big mechanical fan = Cooling running engine ...

Tryed a stock on a 39 Chevy with a 327 and TH400. Did ok till I got to CO. mountains. Blew the top right off it. Put a Walker in Good to go. Be careful no fun trying to get a rad. on the road.

Deuce is right on the mark. You should have plenty of room but get your fan as Deuce says. Walker should make a modern fan with as many rows as you want with an integral tranny cooler and condenser installed just to fit your coupe. When you have it sitting in the original cradle, you then mock up your engine with fan, and tranny to fit perfectly with the radiator. Others manufacturers offer radiators, but my experience tells me Walker is the top of the line for fit and performance. (I like the Griffin that is in my 36 Pickup as well as the Walker in my 36 Coupe so we will see which one lasts the longest)

Wow ,this brings up a point I had not considered.I have a 4.3 v6 in my truck and there was no room for a mechanical fan.So I installed a pusher electric fan,it works well and I have no issues but I do want to put in A/C in the near future.Has any one else dealt with this ? Will a pusher type elec fan handle cooling both the condenser and the radiator ? Thanks for any input,Johnny

A 4.3 and no room ?? there should be plenty of room for a mechanical fan ...

350 V8 fit with a mechanical fan ... and a 4.3 is shorter ...
