Evans Coolant Temps

My fresh 505 stroker is running what I think is HOT. The Autometer gauge is reading 230 at idle with my Edelbrock ProFlo4 saying 220 at idle in my garage at idle. Large garage with the door open. Regardless of which temp I believe both seem really high to me. But before I dump the Evans stuff out for some old fashion 50/50 I wanted to see what others thought as the Evans stuff wasn't cheap.

Set up is below and kept the 440 cool before when it was a motorhome motor with some trickflow heads and a cam. Only change is the stroke, bore, gaskets, rings, cam, water pump and move to EFI
