helllp with cooling issue

New long block, ok.
I think it's a misread of the acual temp then.
Does it perculate after you shut it off when your temp gauge says 200?
(You know, kinda hear it rumble like it's boiling at little in the cooling system) or push coolant out of the radiator?

If not, then it is a invalid temp reading.


Rob,
When sitting at idle, temp creeps up above the 200 mark. While driving it, it also creeps up above the 200. I have not had it where it was hot, sit at a light and then drive again.
I did take it to Athens a few weeks back. Rode & drove fine, although the temp hung in right above the 200 mark.
The radiator is a 2 row.

TrailBeast,
The engine is a new long block that I purchased. I did change out the soft plugs for brass and it was clean back in there. Thanks for the suggestions.
