Do you think a 4 blade will help?

I have a 6.0 head, larger intakes and a 4 speed. No t stat. I run a 50/50 mix of antifreeze and distilled water, and always filled to just over the baffle.

New engine with 1,000 miles. Radiator was brought to a shop and it checked out to be good.

Most of the time around town and some highway I will be about 180. Outside temp 75. I am worried what will happen at an outside temp of 90.

The problem seems to be highway driving 55-60 MPH for a sustained time of about 20 minutes or more. The temp will slowly go to 200, then 220 and remain at 220 while i am at 55-60 mph.

It has never boiled over. One time it went to 225 and that is when I took the back roads home vs the highway.

What are your thoughts on a 4 blade, or any other ideas.
