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

I am putting a '99 LS1 GenIII w/460LE in my '72. Looking at matching up inlet/outlet from engine to radiator and it looks like the coolant flow is backward in the LS1 compared to the original 350. I thought I'd be able to use the original radiator since it has only a few hundred miles since new. What would be the effect of running the flow backward? Am I looking at this situation wrong? Should I be looking for a '99 Camaro rad? Will it fit if I buy one?

Thanks
