Mopar Performance 360/380 running pretty hot

We just installed a Mopar Performance 360 380 hp in my '73 Duster. It is a strong runner and came to me with about 4k miles on it. It seems happiest between 195 and 205 degrees! I cannot confirm whether it is supposed to be running that hot - lots of magnum guys on other forums say 205-215 is okay, but none of them are 'performance' engines like mine.

I have a fairly small radiator that I was planning on swapping out anyway but do any of you have this engine? What are you running at?

Thanks!
