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.
