Switching radiators on my 67 Skylark (300 to 430)

I have a 1967 Buick Skylark. I'm in the process of changing my engine from a 300 to a 430 engine. The standard radiator that came with the 300 engine overheats. I'm just wondering what size to use. If anyone can find one at a decent price or has one that fits, please let me know! Thanks!​


 
IMHO, you can't have too much radiator, and I want one that looks like an OE. I have an aluminum rad with 2 rows of 1" tubes and it isn't quite enough on the hottest days when working hard on high summits with the a/c on (7 blade fan with extra HD clutch). I am probably going to be buying a Griffin, "Exact Fit" with 2 rows of 1.25" tubes:
