another 360/408 over heating

@rod7515 I'm running a very similar combo and the same exact radiator and fan set up except I don't have holes in the shroud. After we got mine on the road I noticed the temps climbing. We chased that demon until we finally put an infared temp gun on it like you did. Once I saw that my cheap AutoGage gauge was off by 10-15 degrees through out the whole range, I closed the hood and never looked back. I drove my car all last summer through the heat with the gauge saying 220 and my car never once overheated. That's because it was really running about 200-205 degrees. The numbers from your original post indicate the same thing?
