Right past 250 on my aftermarket gauge.
That seems REALLY hot for an aftermarket rad. and a 180* t-stat.
Is that a 2 or 3 row rad.? I am only asking because I am in the process of putting a Fluidyne and the same t-stat. I did notice the "disk" around the t-stat, that sits in the housing, is smaller on the Mr.Gasket than on the stock t-stat
Has it done that before, may just be a one time thing. Then again it could have an air bubble in the system, bad sensor/relay, or any number of things. Hopefully it's nothing serious or a reoccuring for that matter.
damn, I don't think that the "M" is anywhere near 250 degrees unless mine is wrong. Mine reads about 180-185 at the "O-R" range, about 185-190 at the "R-M range", and about 195-205 at the "M-A range"
With all that money spent under the hood, go spend 15-60 bucks on a real mechanical gauge. The parts store units for 15 bucks will work fine for you diagnostics.
If this occurs at speed, ensure the air dam is present.
If it happens while going slow/stationary, make sure your fan is indeed coming on and staying on.
The burping idea is a good one. I like to get the driver's-side front up higher than the rest of the system to help air escape. I'd keep burping it - sometimes it takes awhile to get all of the air out if the system was fairly drained.
Good luck.

Place a bib on your left shoulder, coddle the car close while tapping the roof rapidly while slightly twisting side to side. That should burp it.
Well since my autometer cobalt machanical guage went out i have no clue how hot my 331 is getting, it's been 100*+ the past couple of days and on short trips 15 miles to work in the heat it will get to the "O" or the "R" but today i drove to the beach for about 2 hours without the A/C and it climbed to the "M-A" range, how hot is that?? it's got a mr. gasket 180 t-stat, and a Mishimoto radiator and the motor has racked a total of like 300 miles.
The A on mine is 209* I thought my car was getting hot I hooked it up to a scanner, and ran the crap out of it on the dyno a few days ago and it got up to 209* at the A. So i'm not too worried anymore.
