On the radiator setup, you might want to look at PJ Haun's website if you want to put it in the floor.

Definitely want the fan to pull the air through the radiator, not push it as Stephen said. PJ has a fan under the rad and a lip to a create low pressure area.

I was dead set on doing mine that way til I saw Mike (Ruby914)'s setup.



He put the radiator a lot closer to the front of the car than most and then made that awesome carbon fiber ducting. Could be done in fiberglass too, which I might try.

That definitely looks awesome. That's the route I think I'll take if the flat radiator doesn't cool enough. The floor has already been chopped out on mine by the PO, so it doesn't cost me anything to try it. If cooling is insufficient, then I'll switch to the fender well ducted setup.
Thanks for the pointing link!
