Cooling a clone.

"Clone" can be a very broad term & judging from pics here, mine included, many aren't content with doing one "as shipped". Many are done "as raced" or the owners idea of what a streetable Hemi A-body would look like.
So to that end, I'd like to ask : What set-up are you guys using to cool your relatively high-horsepower cars? I'm curious about it All : radiator, fans, pulleys even coolant used. MIne is "okay" on the street but I'd like to keep it cooler still so I'm curious how others are doing it.......
