I am running a 350 SBC with 350TH trans. and it has been running 200 degrees in this hot texas weather(95 degrees outside). now that is when I am doing 75mph on the highway. City driving is like 180-190. I was wanting to put in an ac but that would kick up my temp another 10 degrees at least. I have dual electric fans but I dont think that is the issue since my problem is at high speeds.

200 seems hot to me any advice would be great.

thanks in advance!
