wow finally someone who had the same thinking I did. I've been contemplating this orientation of turbo and radiator for quite some time now. which radiator did you go with? I found one from a 64-66 mustang that would fit in between the core support and behind the bumper, its a 2 row aluminum and measures 19'' x 21 1/2'' x 3". Mine is a street car not a drag car though, and will only be running a 78mm. bravo on the build too, keep up the hard work.
