Running too cold?
Picked up my 68 Firebird this past Feb. It's a numbers matching car with a 400 HO. Spent the past 3 months cleaning up, replacing some parts and fluids, rebuilding Quadrajet, etc. Been taking her out on some road test cruises. I'm running a 180 thermostat. The rally temp gauge in the dash is reading 140 after driving around for awhile. Also running a Thermocap radiator cap that reads the same thing. Put in a new 180 thermostat today and got the same 140 reading after driving over 40 miles. I did see it go up to 150 during some stop and go traffic in today's 80 degree weather.
I am running distilled water with Water Wetter in the radiator for rust prevention. Initial timing is set at 14 degrees BTDC w/ vacuum advance disconnected. 93 octane, no knocking. Using manifold vacuum for distributor advance. Is it ok to run at that temp? Thanks |
