Find and get a Stant SuperStat. They're the best ones on the market. Don't brutalize it with extra holes, etc.
Normally if it gets hot when your cruzn it because your cooling system is undersized, hence like the radiator is to small. You have all the air you need at cruzn speed.Idle... Based on the replies (thanks to all) I would like to try the 180' thermostat, but again, what kind/model etc. ?

Getting hot at idle is a different story, could be two fold, 1st and foremost - not enough air.
Second, low coolant flow at idle rpm
Both very common problems
Go a head and try your 180 thermostat, i doubt it will cure it, but you never know until you try.
I run a Milodon High flow stat 160 in my 340 with factory A/C, even on the hottest days it rarely gets above 180-185 at idle, never gets above 160 at cruz speed.
I tried a 180 stat at first and when a use the A/C the engine temp would go up to 190 and above and then would struggle to get back to 180.Why do you want the engine at 160 at cruising speed?
Where you are located I would apply a 180 degree high flow thermostat.Didn't have overheating problems with my car before, but I rebuilt the engine this year and the temp seems to go to 170 180 to 200 .. And rising while I'm in the city or stagnate in traffic but once I get moving it will go back down but after driving 20 mins once I get back to city driving it goes up and fast to 200 and I start to panic.
I never had this before.
Now let me explain a cpl of things.
Like I said this year it a new rebuild, when the car is cold the oil pressure will go to 80 no problem (even higher just under, 90) once it starts to warm up it will stay around 40 lbs and idle at about 25 to 35.
Then, I never had a thermostat in the car and never had problems with the car going over 180 but now like I said it goes up and fast.
I have a nice rad (forget the name might be those Be Cool or looks like it) never gave me problems.
I'm thinking maybe I just need a thermostat?
What type, degree should I use?
I have a 340 6 bbl (550 lift solid cam, 4 speed car, 4.10 rear gears)
It's a weekend driver and a daily driver if the weather is good, I put on this car this yr in just 2 months close to 2000 miles, I drive it everywhere to the track, to work, to the market.
I never had this until recently.
Any help I'll be truly grateful.

Read post #31So can someone tell me what thermostat I should get, 160 or 180.
I was leaning towers 180 but I'm not sure as I'm not savvy to these things.
One more thing, I looked to buy one from Jegs (Summit as well) and see that Milodon makes a nice stat that also is way more expensive than the others, (30 dollars or so) but it's reviews seem to be almost 5 stars (out of 5) so I'm leaning n that way @ 180 degrees, any thoughts from the "Go to Guys" ?
Thanks.

uhh, what?@kursplat
usually for me, as I don't their water pump.... What they say.
Good article.
My rule of thumb for cooling systems -
1 Your block and heads water passages are dirtier than you think.
2 Your radiator is dirtier than you think, and possibly fouled with rust/well water instead of distilled water.
Thanks.Do u have Evans waterless coolant?. If not a 50/50 mix works. Premixed? But u can’t Straight antifreeze. I run a 195 T stat. Kim
