Got a 67 RS/ss 350 powerglide rag top,at speed(55 or above) temp starts to climb and will not come down untill you drop below 55mph.Been throught all the items that generally fit this profile,added an extra cooler to trany too.At one time or another everything has been replaced and the trany has been rebuilt twice.Anybody got any ideas?
Would think the radiator too but had that recored and added a core while I was at it.Carb is something I have not looked at thought,will see if it my be the case.Also found today that the SW gauge is off, was 90 in my shaded garage ,gaugestarts at 100 and car had not been out or in the sun for days,gauge said 105,will look imto that more too!Thanks <BLOCKQUOTE>quote:</font><HR>Originally posted by lnjstreetrods: Sounds to me like the carb is lean. If it is a Q Jet the metering rods will stick down and lean it out.
You said you have done all the other stuff, but unless you KNOW that the radiator is good I would suspect it.
Do you have a thermostat in the cooling system? Some people think removing the thermostat will make the car run cooler, but at high speeds (high RPM) the coolant will pass through the radiator so quickly, it doesn't get cooled down enough..just a thought. Good luck
