I just bought the car at an auction, its a 87 caprice with a 305. I drove it down the road a lil ways maybe 5 miles and the temp gauge was around 220-230, i thought it was overheating so i have replaced the waterpump and thermostat.I havent drove it since to see if it goes to the same temp, but was that normal? I wasnt running the a/c only the heat and it was on low, but if someone could tell me the reg running temp of this car i would really appreciate it.

220-230 that is a bit high...
My 305 Silverado runs about 150-180 on average. My engine hit 230ish once because I had two bottles of Barrs running through my system, too much can plug radiator vanes. Its entirly possible that you have a small coolant leak and they dropped in stopleak to avoid the repair. Try thoroughly flushing your system with a flush kit and look for leaks.

EDIT:
Dont overlook replaceing your radiator cap! lol easy to forget

Did you check to see if your radiator was clear? I had issues with overheating, I had found that there was a bunch of crap clogging up my radiator it wasn�t getting any airflow, so I shot her clean with a pressure washer, no problems now

Also is your fan cowling still there? If it isn�t you may not be getting as much airflow as you need

let us know how you make out
