Ok,

So I am not at a total Loss on why my 400 is running 210 at idle. Start the car and it will just slowly get to about 210.

This is what has been done.

-All filler panels verified and good. Two rubber beside the radiator, Upper steel and lower fiberglass panel.
- HD clutch with 19 inch Fan half inside factory shroud.
-New Champion 4 Core Aluminum Radiator
-160 thermostat with two 1/4 inch holes drilled.
-New Flow Kooler Water pump
-New Divider plated clearenced correctly to the pump.
-Distilled water with Water Wetter

Timing is at the mark closest to the top of the timing cover. not sure what degree that is.
Running a MSD complete setup timing is 36 total

So Im at a loss here...
