Swap Overheating
My 91 RS had factory 305 with all factory water pump, 195* thermostat, 230* fan switch, stock radiator. I swapped to a 350 Carbed and left the 195* thermostat, new stock water pump, and new stock aluminum radiator. Well the car would run around 200-220 all the time but no more. I figured that was to hot so I installed a 200* fan switch and a 160* thermostat. Well now the thing will be running around 180* down the highway and then jump up to about 230* and I pull over and wait for it to cool down. What is up? Is the 160* thermostat letting the coolant flow to long therefore heating it up to much by not letting it cool in the radiator? Any thoughts?
Thanks,
Kevin

before with my 305 I used to have similar problems.. it appeared after I had to replace my water pump though.. sometimes the tolerances on those things are a little off..
