Just my two cents. Not to discount the comments regarding the rad, they're certainly valid and a capable radiator is imperative to keeping the engine and transmission cool.
Also though, a newly built engine will generally run a little hot until it's broken in and tuned correctly. How lean are you running with your carb settings? Are you sure your timing is dialled in? Why are you running a 160 thermostat? Isn't a 180 the recommended temp? Are you sure there's no air trapped in your system?

After installing the new 4 core with shroud, 7 blade fan and 160 thermo, the 300 runs hot, close to the upper limit. Have not driven it yet, only raised the idle to 2k, and the gauge dropped a bit to the left. The block is a new build with 200 or less miles, clean on the inside. The cap is a 13 #. No leaks. runs hot. Any thing look incorrect ?
