I was told that a 4 core doesnt necessarily help because it reduces the airflow because of the additional thickness. So you have to balance that against the additional volume.

Thats why I ask.

I have a 3 row in a 65 401 buick riviera (bored 30 over- 35,000 miles) and the radiator is 1 year old but this summer its just getting up to 230 (air temp is 100 and a/c on - so maybe I am asking for trouble). and if I get in stop and go traffic it goes up to 235. I have checked/replaced everything (thermostat, tried flex fan, new hoses, shroud, timing, even changed the head gaskets) and now I am thinking I should have gotten a 4 row. I cant put a pusher fan on the outside because of the headlight motor.

Unless I put a small 9" fan . Will that help? since it gets hot even on the freeway I would think that airflow is not the problem.
