Radiator overheating already - The 1947 - Present Chevrolet & GMC Truck Message Board Network

One question, is you "super cool long water pump" designed for V belts or is it for a later engine with serpentine belts? Missmatching the pump and the belts will cause the coolant to want to flow in reverse and not flow much at all. I'd make positive that I had the correct pump for the belt setup you have.

You may be correct on those aluminum radiators as some guys haven't had a lot of luck with them but it sounds strange to get that hot and puke that much coolant without being stuck in traffic or pulling a heck of a load.

+1 verify it's not a reverse rotation pump. Recheck the basics, Aluminum radiators generally are not the culprit.
