Dave at the car show this weekend, one guy I talked with had a pusher electric fan setup. He said he never has problems with it getting hot even sitting in traffic. Most of the others that were using electric seemed to have pullers. I like the front of the engine clearance for the pusher fans. Yet I don't have any experience with them myself! I will have to go electric pusher on my truck due to space issues, so I'm hoping to pick up info from this thread too!

It's generally accepted that pullers are more efficient, especially when used with a shroud that covers the entire surface of the radiator core. A SPAL is something like 2700 cfms, and they make a slimline version that I have had good luck with.
I would have suggested that you use a SPAL 16 incher, but you only have 15 inches to play with, so instead I think two 10 inch ones , staggered, on a shroud would work well. From what I understand, two 10 inchers do not equal a 20 inch fan in efficiency, but they do move a fair amount of air.
The shroud should be made so that it is about 1/2 inch off of the surface of the fins, so that air can be dragged clear across the core. Either aluminum or sheet metal can be formed to the shape you need, then you can cut the correct sized hole(s) for the fan(s).

Pushers aren't working for me and I have the same space issues.

I've been looking at this thing, but it's pricey.
