I am monitoring coolant temp with a ScanGauge. The radiator has a tunnel between it and the grill and valence, so not a lot of other air is getting in. There are some holes and gaps but not a lot.

I'm interested in what port size others with a similar sized engine are using.

I have another valence cut and am ready to put an opening in but trying to decide how big. I will probably wait until I see what the current ports run in hot weather. But if I see a lot of temp cycling (fan use) or temps much over 210, I will probably go two times the area of the current ports with one oval opening in the middle.

The location here is So Haven, tropical southern Lake Michigan.
