Electric fans for an RB A-Body?

Well; it's almost time for the motor to go in the car, and I want to have everything ready to go.

I have an AFCO aluminum radiator that came with the car when I bought it, but it had a dinky little electric fan on it. What is the best electric fan setup for an RB A-Body? I was looking at the Chevy HHR fan... lot of guys using them... but I don't think it'll fit....
