Radiators: Griffen vs Northern

My griffen runs hot but my engine is far from stock.

My 505 is far from stock. I had the car slip off a floor jack and bend the front valance and radiator, I straightened the valance , and pressure tested the rad. , its still in the car today with no leaks------it is a griffin 28x19 crossflow , with 1 1/4" tubes ------------IMG_0539 (3).jpg
The circles are drawn locations for elec fan layout , that didn't work , meh.clutch fan does . I experimented with fans for two yrs.IMG_0469 (3).JPG
The shroud has been re worked 5 times , and is now shorter than this/ getting kind of ugly too .
