Are you saying you're warm up happens more slowly, or that you're final operating temp is lower? A grille block can potentially slow warm up a little because the engine doesn't have to work as hard. That being said, I would think the effect would be really small.

I can't quantify it unfortunately, the car is OBD1 so I can't get a quick answer. I was talking about final operating temp.
