Which combination is best overall for engine cooling and visual appeal?

You sure don't ask for much, do you? LOL
The best answer is...it depends. First, more info is needed.
1) What year Camaro? The amount of available mounting area behind or in front of the radiatoris a factor.
2) What size engine, big or small block?
3) Is the engine stock, or hi-perf?
4) Has the block been bored out, or standard bore? Overbored engines have more of a tendency to run hotter.
5) What kind of radiator are you using?
6) Does the car havea healthycharging system?
7) Are you running any underdrive pulleys?
8) Do you plan on doing morestop and go driving, or more open road?
9) Are you planning on racing the car?

I agree. All your points should be taken into account.

what does all this have to do with it? it's just like the question: what weighs more, a pound of feathers or a pound of bricks? it's still a pound

better cooling is better cooling, no matter how the engine is built

It has a lot to do with it. If you have to ask, then my answer might not mean anything to you, but I'll try...
The question was "Which combination is best overall for engine cooling and visual appeal?"
As you pointed out better cooling is better cooling, won't argue that one. So what is better cooling? I would say running a belt driven fan in conjunction with an electric fan. Does that have the best visual appeal? NO!
So I guess that wasn't the best answer.
A few of the other points I was making is that a lot of times the engine dictates how heavy duty your cooilng system needs to be. A plain-jane small block isn't going to be as demanding as a heavily bored/built engine.
A 4-core aluminum radiator, even on it's own, will run the engine cooler than an old 2-core stock radiator, so more cooling fans wouldn't be as necessary.
Charging system: if alternator output is right in balance with the way the car is now, then adding one or two electric fans could easily make the battery go into the red zone.
If the car is going to be raced, an electric fan would be better since it sucks less h.p. from the engine compared to a belt driven fan. And the electric fan can be wired to switch off when wanted.
The cooling system isn't a one-size-fits-all prospect. Going overkill, if not really necessary, can have it's drawbacks, both economically and aesthetically.
Hope it all makes sense to you now.

you make a couple of good points, but I think you are trying to make too much out of his question. I'm not trying to fight with you here (so please don't take it that way), but a lot of your variables, have a lot more to do with things that should be taken care of before the fans even come into play

I am pretty sure he posed his original question/poll, with all things being equal and the car being a good runner with a good charging system

it was just a question of what is the best all-around way to cool an engine

No problem, I don't. Even though his question itself was a simple one, by his poll he looked like he was trying to weigh everything over carefully. I was just trying to make him say...hmmmmm!

when you said in your post (directed to me)..."if you have to ask", I had to laugh, because I knew exactly where you were going with that.

others on the other hand, I'm sure you made think..hmmmmmm?[sm=hiya.gif]
