So this will not be for me, maybe someone else here with deeper pockets. I have been going around a dog and pony show trying to get an aluminum radiator made for our C6s. First we tried with this company in China and I am sure you can assume how that went. Next I shipped my broken radiator to Fluidyne who quoted me ~$600 - $700 for a custom radiator. Fluidyne after 6 weeks said they can not make it for me because the inlet and outlet bungs are special order min (50) quantity. Next I sent it to bell intercoolers. Guy there Jonathan Gwinn currently has my radiator and has generated a CAD for it but is asking $2,400 + shipping.
So if any of you want this all aluminum rad, there is where you can obtain one. Let us know if you land one, would love to see it…
