Put a Champion 526 radiator in a 71 swinger?

I've got a Champion 2-row 26" in my 71 Dart with a 360 and mechanical fan.. had to drill a couple new mounting holes on the radiator mounting surface to get it to bolt up, but it fits fine. I would like to end up going with electric fans instead of mechanical, because summers here in Sacramento get pretty brutal, and I don't think it would cool well enough with no shroud right now.. but the whole electric fan thing looks like a major PITA with some of the wiring diagrams you guys are posting

I didn't have any issues cooling my 420+ hp 340 with my 3 row 26" champion and a plain old flex fan. In fact, it ran too cold, and was really hard to warm up first thing in the morning. Which is one of the reasons I went to the electrics, only get the fan when I need it instead of all the time. Shortened my warm up times by a ton, and still plenty of cooling.

The wiring isn't all that bad, and I HATE wiring. With the relays, all you really need to do is find a couple of constant 12v sources, and a switched 12v source, to run to the relays. The constant 12v source for the fans is best pulled off the starter relay B terminal, because of the load it pulls. That actually makes that one really simple. The constant 12v source for the controller can be pulled off the fuse block. Switched can be pulled off the fuse block.

I also pulled my fan harness off of a Contour at the wrecking yard, so that made the fan harness a piece of cake. I deleted a couple of unnecessary wires out of it, but that was it.
