Ok, Josh'* temps have come back down to normal, but his coolant dropped a little in the reservior. My theory is that he just filled some airpockets after the top end teardown. Now that they've filled, he'* running cool again, and the coolant level went down. These were my conclusions after talking to him and his Stepdad, anyway. Both say the car is strong, good power, and no unknown odors. I haven't driven it since the work.

Can anyone confirm my theory? Anyone seen this after a lower intake r&r?

Something similar happend to my friends LT1 camaro but I don't know how much can cross reference to those two motors.
