[DeTomaso] need advice before I cry

[Asa Jay Laughton]

By the way, I found one of those handheld point and shoot thermometers a 
real blessing while doing this.  I picked one up from Napa, not the most 
expensive but it did what I needed it to do.

I have a second temp sensor hooked up to EFI system in thermostat upper pipe, and that reads 160, so I figure must be air in block still and run it a little more.  Dash gauge temp goes steadily up to 260 (end of reading), and temp sensor in upper pipe remains at 180.  car runs fine, and I wonder if dash gauge is no good (but it worked fine on maiden run few weeks ago).
