Why did you go from a three row to a four?Sometimes a thicker core will run hotter because airflow is restricted more with the added thickness.

I installed a new and now my Coronet is definitely running warmer than it should. 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?
