I'm about to spring on a new aluminum cross-flow radiator for my convertible tomorrow on summit, any recommendations on an electric fan to keep this bad boy cool? mild/moderately built 440-5 speed manual in a '70 B body (no a/c)
I know it's an oxymoron, but I want a decent electric fan, but I don't want to spend an arm and a leg for one either..

The OE fans are much better than most aftermarket... and lower cost than the top end aftermarket. The Chevy HHR fan is supposed to be good. Available from a Chevy dealer or several knock-off's on the web.
PS... the belt driven thermal clutch fan with shroud works really well. And has no added electrical loads and wiring... but you asked about electric.
The OEM HHR fan? Coincidentally I work in the service department at a chevy dealer, I'll have to check pricing on that tomorrow! How are they getting wired up? some aftermarket thermostatic switch?

The HHR fans are cheap and move decent air. You have to hack the shroud to make it work. The 2005 and newer Mercedes C-class fans are AWESOME and a near perfect fit. They make the HHR fan look like child's toy. Find a used one at the wrecking yard (or LKQ) and drop it on. The 2001 to 2004 C-class fans are a wee bit different and need a controller to operate properly. The same goes for most aftermarket Mercedes fans. A Moparts member is working on that and we're days away from testing the unit. Here's the correct style Mercedes fan sitting on a trashed 26" radiator:  Here's the two different style Mercedes fans:  Do not use the fan with the heat sink as seen in the top of this picture until you have a PWM fan controller. The bottom fan is the best one to use with an on-off switch or simple controller. Read the Monster Cooling Fan thread for more info. Here's the HHR fan for comparison:

I saw your thread on that previously, and it looks cool, but used ones are still expensive.
I can't pull it up on the LKQ website, but i did on car-part.com and they come up, but are uber-expensive...

The HHR fan or just about any other electric would be wired through an aftermarket switch and relay. A standard 30 amp relay will be marginal for a high capacity unit like the HHR fan. Use two relays or buy a bigger single relay. Summit and others offer several kits with various types of temp sensors and fuse/breaker choices. Some have adjustable setpoints. The big relay or the double relay may require modification of the kits. Use 10 guage wire for the power feed wires. 16 or even 18 will work fine for the relay control wires.

the issue is that you need a fan from a later model or it requires a special controller. I think it's 06 or later. this fan you quoted is likely modeled after the earlier fan. Not the end of the world, but it is a small added expense I don't know what you would do if it broke a few years down the line...
I'd look for one from a local yard that's actually used and came from the later car. depends on where you live. around here it's likely easy to find one because everyone seems to have mercedes money except me lol.

Read my monster cooling fan thread listed above. It'll list everything you need to know about using the Mercedes fan.
The early fans will die if a PWM controller isn't used. The later fans (and those in a 2004 and newer CLK) will work fine. Look for the heat sink. If it's got one don't run it until you have a controller.

The Mercedes fan would cool the twin turbo 440 in 100 degree Texas heat. The turbos were just inches away from the radiator and I had hot exhaust pipes running up and down each side of the engine compartment. It could cool the engine during repeated hard pulls under boost. We beat on it for more than three hours, never going more than a few minutes without a hard run. The temps were in the 90s that night and the engine never ran hot.
The MB fan draws air from more than 95% of the radiator core. The HHR shroud is much smaller and therefore draws air from a much lower percentage of the radiator core.
I would much rather have too much fan than too little.
