I'm new and have a 64 Impala i'm workin on. She has a 454 w/ an estimated 450HP. She hasn't been started or dynoed but desktop dynoed ( I know not accurate)!

I live in Nebraska where it's HOT during the summer (90-100*). I'm going to use my factory radiator that has been recored and cleaned to start out. If need be I'll get an aluminum if the fan doesn't work well.

What I need to know is what kind and how many cfm fan do I need? People tell me I need a 16" 3000cfm fan. I've also been told about the Black Magic Flex fan that puts out 2800cfm and has a shroud.

What do you guys think about fans and cfm for my application?

Thanks Pat!
