What should be my temp?

I have a 1973 360la in a 66 cuda. Bored .30 and zero decked. Stock crank, KB pistons, comp high energy 268 cam, ported polished heads, air gap with a 2 inch riser, holley 750, hedman fenderwall headers. 9.5-1 compression. I have a 22 inch champion radiator with dual fans. I'm guessing I'm around 385hp. I idle in park at 1100 rpm and in drive at 900-800. What should be my max temp? Thanks in advance.
