Bill, Been thru all this.......got the tee shirts and check stubs to prove it. What are u using for a temp gauge?What you need to do is put u in a high performance water pump to circulate the water faster thru the radiator. DO NOT use a 160 thermostat. If you do achieve this temp your engine will run like a 3 legged dog anyway..
Get a high performance 180 thermostat. DO NOT drill holes. Hope you do not need a shroud. But that is next. OlliePS..mistake one...needed a aluminum radiator, mistake two, thicker is not better, bigger is the answer. Now my critics will say..its only a 318 and the factory stuff worked many years........and the answer is VERY simple.......it will only get worse as this new & improved fuel..E85 hits the streets....

It was actually running hotter with the previous t-stat in it then I changed it. I did add some water wetter.

By the way Wetter Water really does work. Id try some with your case (and a160 stat).

When I get moving again, the temp will come right down, but it's still reading a little high compared to the 3-core. I'm wondering if I'm going to have to spend the $ for a shroud, and a Flowkooler water pump.

Sometimes a thicker core will run hotter because airflow is restricted more with the added thickness.

Here's the list... 318 Poly, Mild cam, 4-bbl New 4-core copper radiator (US Radiator) New 180 deg thermostat New 16LB cap No known issue with the water pump. 7-blade fan w/ clutch (seems to be working) ~1 inch from the rad. No fan shroud I swapped the previous 3-core radiator out because it was leaking. With the 3-core setup (no shroud) it never got as hot as fast as it does now. In fact after sitting just a few minutes at a light, this 4-core gets as hot as the 3-core rad did on only the hottest days in July/August. I know the lack of a shroud is 1 problem, but I just can't shell out $250 +$50 for mounting hardware for it right now. Considering I basically swapped only the rad, it should be acting better than this. Any thoughts?
