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

1 16" mechanical fan with a shroud will cool that no problem. I also use Evans in my filled block 511 and it cools great with mechanical fan and water pump. I have since switched to all electric with dual 12" spal paddle fans. Will see how this works, but I think its gonna be fine. Last year I tried dual 12" spal curved blade fans and it would not cool properly, ran 218* in the heat driving. Spal has 10" paddle fans, but they only move 1100cfm each. Not enough in my opinion. I have a 26" radiator in my A body and dual 12" fans fit nice. Look at A1 Electric, they have all the Spal fans layed out with specs. Andy runs a Mechanical fan, they will cool just fine with a shroud. Oh and my 12" paddle fans move over 3200cfm together, I think that's what it will take in the heat.
