Are you running hot on the highway or idling around town? Just saying maybe it's not the radiator
I tried everything else before I changed my radiator and found a system that works for my mild(maybe 570) combo. My engine gets up to around 200 when I cruise around on 90 degree days but that is really not overheating.

The car isn't on the road yet. I had the stock radiator in front of the Stealth headed 383 that was in it, and idling and 55-60 it never saw much over 185. When I got on 23 heading north and hit 70-75, it was up around 190.
I have a 440 Source pump and housing on the engine going in it. That's all the cooling system I have figured out so far.
I don't want to cut the core support for a 26". I haven't decide on mechanical or electric fans, although I'm leaning towards a clutch or flex fan.
