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

I never had any luck with the aftermarket fans. I had twin Flexalite fans and they didn't come close to cooling my engine. I bought a fan for a Chevy HHR ($50.00 through RockaRock Auto) modified it to fit my 26 inch Champion radiator. My Dart now runs 190 degrees in traffic. Actually it runs a little warmer when driving down the road probably about 200 to 205 but it runs much cooler when I'm sitting in traffic.
My Dart used to run HOT in traffic (230°) and I would be rushing to get to the parking spot at the cruise so I could shut it down.

The above mentioned fan is a Dorman direct replacement for a Chevy HHR. $50.00 brand new from Rock Auto.
