I've been looking at that too. Most electric fan companies do not recommend electric fans for over 400 cid. They say that you need somewhere around 2800 cfm to keep a big block cool (depends on the engine of course). Most electric fans only pull around 1500 cfm. A clutch fan pulls plenty, especially with a shround.

Now, we've all seen big blown engines with eletric fans, so I know it's gotta work. I'm planning on running dual 12" or 14" fans in my 67 mustang. The radiator is a 3-row 24"x16". The fans I like the most are by Hot Rod Air, although I'm sure any major manufacturer would work fine. One thing to look for is a thermostat. Some aftermarket fans don't automatically come on, so you have to wire a thermostat into it. I think painless wiring has a kit for this. You can find it at Summit.
