That's a nice setup. Understand when I say this, I take NOTHING away from it whatsoever. However, you have one HECK of a radiator if it never has idle temps above 190........and I believe you. "Most" high performance engines do require that magical "around" 4000 CFM number in order to keep cool at idle or slow speeds. That's a nice install you did blocking the overlap areas as you say. Most people don't think of that. Do you have pictures installed? I'd love to see it. I'm sure it's a neat fit.
