NEED A RADIATOR...which would be the better choice?

[90blzr]

Wondering which one would cool better....a smaller 4 core...or a bigger 3 core? Big block 3 core (34x19), or a small block 4 core (28x19).
Had a post in the garage, but not much response, so I'll try here.
Core support will accept either one.

Gonna put dual electric fans on it too.

Thinner, larger radiator will perform better. More cores "restrict" airflow which decreases ability to cool.

This is why 2 core aluminum radiators work so well.
