high water temp issues

I get to the highway and thats where it warms up. Once I get on the highway I'm at about 190 and then it slowly creeps up from there.

I just checked and this is the rad I have: 3574658 1972 A 22" 318 340 Both A/C

Heating on the highway is not a shroud problem. Water flow or not enough radiator

Dirty block, heads, radiator. Something with the water pump. T stat not opening.
