Haha, I have no plans for teeth as of now.
Day two of the grill block shows its definitely not too large. Yesterday it was about 30 degrees out and I hit a max coolant temp (according to the SG) of 207. In summer, without the grill block, I was hitting 212 so I'm actually running cooler than summer still. I'm not sure why the SG is reading high to be honest, it has a 195 degree thermostat in it. Anyway, today it was 6 degrees out and the coolant didn't even hit 180 on my way into work this morning! Its a 20 mile drive, so it has plenty of time to heat up. I gotta say I was a bit surprised by that.
