I was wrong, mine runs around 200 and 210, I had to look a little closer.

most big blocks run 200 210 its normal if the car wont start when its at operating temp but will start when it cools down change the ignition module would be my advise from my own experience

newer cars run that hot because they need to so they can burn more efficiantly to pass emissions but their clearances are different than older engines
another problem people have is that they try to run too cool of a thermostat. if you try to run too cool of one and the engine can't dissapate (sp?) the heat quick enough, the stat will constantly be open and you will onlykeep getting hotter. sometimes if you can't keep your engine cool, you can runup to 10 degrees cooler, by running a thermostat 5 degrees hotter than you are currently running, because it will stay closed longer and give the coolant in the radiator longer time to cycle and cool down

after watching mine it runs around 195 to 205, depending on how hard I am on the gas....everything on the car is new except for the intake and carb....I get the readings from the heads..and the headers heat the engine compartment alot..I would like to run about 180 to 190..

ahhh no, most big blocks don't run that hot. most engines don't run that hot normally..period!

Wow thanks for the great info guys. As for the ignition module I currently have a MSD 6A p/n 6200 and a MSD blaster ss ignition coil p/n 8207. Do i need to replace both? Or will theMSD 6A be fine? Please info in this would be great. Here are some pics.

Most mechanics will tell you that coils will last must longer than the modules. Mods burn out but as for replacing the coil, have it tested first at the local parts shop. It's probably still good.
