i have a 84 camaro, with a newly rebuilt motor in it and it has a over heating problem, i would be running about 2500 rpm and it will slowly climb on a pretty humid day, nothing to bad but it will climb, and i just changed the thermostat, but when iam toolin through town at about 1500 it seems fine. runs at about 210. i have a 195 therm in it. my first question is why is this happening? is it still not opening up even tho it is brand new? and my second question is what is the max temp on a small block before it starts blowin stuff? becuase now it smokes like crazy, blue smoke, and i have a hudge loss of power. did i blow a head gasket? please tell me the good news first. lol. thanks!
