340 coolant temperature

Made some holes in the shroud, not big hole just lots of smaller one.

Change the stat to 180 (it was 160) and took it out for 40 miles drive on highway at steady 55~60 (3000~3500rpm).

It takes along time to reach normal temp 190, then it stays there, till you push it a little more. Temp goes up to near 200.

I stopped to check and noted a little coolant from the rad overflow pipe.

I have not tried driving with higher than 4000 rpm.

Is this normal running, or not.
