Blueprint 408 cooling system questions.

Here’s something for anyone wondering about why something runs hot, or hotter than you might think it should. Take my vans previous setup as an example: 410 stroker with ceramic coated headers, iron heads, mild cam and 9.75 cr. All under a doghouse with an large tube two-row aluminum radiator, 13” fixed aluminum 6 blade engine driven fan, a parts store 8 vane pump with plate, and a 160 thermostat. Cruising and racing temps ran anywhere from 170-180, at stops it would climb a little as I had no shroud. But worked fine no issues considering the doghouse. Then for cooling between rounds at the strip I installed a high cfm electric Derale rad fan w/shroud, and a billet Moroso electric water pump, with a gutted thermostat. Now it runs about 190+/-. Better at idle because of the shroud, but otherwise it runs a little hotter, still acceptable though. AND, I’ve added more air intake to the front of the radiator with an underside scoop. So why the increase in temps. What is happening with the flow of coolant that has caused the increase in temps? (I know why by the way):)
