Help me design my cooling

[GTO Jack]

I have a 1965 GTO and I am installing a 430hp LS3. It is and will be stock from the GM ECM. In the past the early GTO's struggled with cooling, must be the front end design played a part. My car came with a down flow originally. They came with a 15.5in radiator and if you got A/C then the radiator core was 2in lower at the bottom so it got a 17.5in radiator. I have the 17.5in version. I don't know if LS engines run hot or if they are easy to keep cool. I have the cooling connections as shown in the picture. I feel like even thou the upper hose connection is slightly to the driver side it may better to run that to the passenger side. I will be adding a couple Spal fans after this is in place. I am open to suggestions.

I'm running a stock replacement radiator in my 64 chevelle with fans of an ls1 fbody. It is a cross flow with plastic tanks. Haven't had any problems with cooling, although my front end is wide open.
