Getting Hot

[mikes67]

I need some help.
I have a 67 chevelle 300 2 door sedan with a air conditioned 396 that i am have some over heating problems with.

It all started after i had my carb and dist overhauled, it started running a little warmer that normal so i dropped the thermostat to a 180 and put a fan blade extension in to move the fan closer to the radiator helped a little.

I thought if i put a aluminum radiator in that would solve some of the problem and look good did not work tem actually went up from 180 to 190/210 idle would come down when moving, dropped a 165 thermostat in temp went to 185/190 idel sometimes it would creep up to 210 if i had to sit longer or turn the ac on it would really run up. I bought a pair od 12" fans and shroud and things really went wrong the temp went to 210/220 idel and 220/230 crusing no ac take fans off it runs 220/230 crusing scary with aluminum heads.

This is a three row aluminum radiator, i have bought new spal fans waiting to install if i can figure out why the radiator won't even cool without fans on. I went bach to stock fan and shroud and it runs 220/230
