350 chevy overheating
I have a 73 Nova that I built a .030 over 010 motor for. It has .125 dome trw pistons, World Products S/R 202 heads, Comp cam .515 lift-300 duration cam. I have tried a be cool rad., a stock hd rad., flex fan, puller electric fan,a 195 thermostat, and a 180 thermostat. It idles at 1150rpm, and will overheat sitting there with the fan on to 250 plus. I have not driven it yet due to this problem. Any suggestions? I have good circulation in the rad with a new stock H20 pump. Please help before I get out the sledgehammer!
