Working on a project, and finding I have little to no room for a mech fan, so I'm considering electrical fans. My issue is that there is very little room. Per the photo, assuming I change nothing else, I have an outside area of 27 x 17, and only 1.5-2" depth between the radiator and front of the motor.

Does anyone know who makes good quality ultra thin cooling fans??

Thanks in advance......

I used the Ford Contour fan set up. I did have to shave a bit off of the shroud, but so far so good.

I also used the Contour fan set up with a Champion 3 row radiator. I had to change my water pump pulley bolts to button head instead of SHCS, otherwise I had clearance.
 
Thanks for all the suggestions. i will check out the ford contour set up - I've heard the chevy equinox also has a pretty good set up as well.

pull vs push is also an option, but not knowing any better, i'd be concerned about reducing the cooling ability of the radiator by putting fans in front. dunno?? any thoughts on that concern?
 
What's the overall thickness of the ford contour set up - depth front to back?
 
Good question about pusher/puller flow rates. My understanding is no difference, same resistance to flow, just different sides of the radiator.
 
I used one from a Chevy HHR, $50.00 from Amazon brand new. It will require mods, I am running the Champion 22" aluminum rad and it keeps my 418 Stroker just below 200°. I will get pics.
 
I picked this pair up years ago. Turned on end they fit perfect across the 26" radiator and lack about an inch at the top.
Don't know if they are still around these days..……….

I bought my radiator, shroud and dual electric fans from Challengergary ... or was it Challengersteve

on FABO. It fits in that same tight spot. I don't have any better pics with me. I can take some when I get home tonight if you like. I love the looks of my setup and it fits well.

It's about 3" from the radiator to the back of the shroud, about 3 1/2" from the radiator to the back of the motors but they're offset. I run the same Contour fan set up in my Duster with a 26" 3 row Champion radiator. I have a decent amount of room using a set of March pulleys and button head hardware.

Not true at all. The fans being in front of the radiator mean that whenever the fans aren't running, they're obstructing the airflow through the radiator. So, any time you're moving at a decent clip (ie, when the fans shouldn't need to be running) a pusher is lowering the efficiency of the radiator. A pusher also can't use a fan shroud because it would block even more air, so, unless the fan somehow covers every inch of the radiator it won't push air through the entire core.

A puller, on the other hand, doesn't effect the airflow through the radiator when the fans aren't on, and if the shroud covers the entire core then air will be pulled through the entire core.
 
Thanks to everyone who responded, it's all been very helpful. Due to the lack of space I have (roughly 1.5 - 2" only), I'm electing to cut the radiator opening a little bit and enlarge the hole while using dual pusher fans. I've read both arguments for and against pusher fans, some of it repeated here, but my selection is based more on practicality and space than which is more efficient. Truth is I'd rather use a regular mechanical fan, but I have to run with what I have room for, so pushers it is!!

Yup, with that amount of space you don’t have a lot of options.

That’s a March serpentine set up on a big block yeah? What radiator is that?

Griffin 26" 3 row

We're shoe horning a FHO Hemi into an A body, so space is at a premium.....

Same question here: I have a 68 Dart with about 2 inches between the water pump pulley bolts and the radiator, so the depth on the contour setup width at the water pump pulley (center) is critical. Thanks!
 
I’m working with someone to come up with the final configuration, but because we have over 7-8” in front of the radiator, we’ve changed from doing pushers on the front of the radiator to building a frame and doing pullers with a shroud on the front. The size we’re going with fits the opening perfectly and flows more cfm than the pair of pushers we were going to use.
