Help I can't take no more! Let me tell my story, I have a 69 camaro that about 8 years ago I built a 30 over 350, out of a 79 truck block, nothing special, low compression, mild cam. It always ran cool, never got hot, stock fan 3 core aluminum rad. Life was good. Then last year all my trouble began. I installed a vintage air ac system, there was a clearing issue with the water pump and the new two grove pulley so I changed the water pump, well I was out of antifreeze so I didn't top off the rad, I would buy more later , before i drove the car, right , months later I need to move the car and thought I should drive around the block, be good for it, right I forgot that I had never replaced the coolest, dum ***. So it got really hot 250, got home cooled it down, water in the oil. I tore it Dow to long block ,thought blown head gasket,but no the intake gasket had failed letting water into block, everything else looked good ,replaced all gaskets, but still runs hot 230 /250 just going around block, I go to electric fan puller 25,000 btus behind rad. Fan shroud , switch to 4 core rad , try different water pump, run 160 o thermalstat with two small holes drilled , jacked up front of car to burp cooling system, car still runs 200 degrees after driving around the block, set timing at 12/16 degrees advance with vacuum plugged, have hei dist, still runs 200 deg , fed up!!
