hb, (wish you guys would include your real names)
Did you use an AC Delco oil filter ? If so make certain that it is the correct one. Some of the aftermarket filters do not have the correct anti drainback valve in them and will allow cause the lifters and bearings to be noisy for the first few seconds until the filter fills up. Also, make certain you used the correct weight oil, I am pretty sure it should be 5w30. I have not heard of any other noise problems with those motors when cold. If the filter does not take care of the problem, it is certainly still under warranty so I would be back to the dealer ASAP.
By the way, and this is just my opinion, 7000 miles is way too long for the first oil change. If you plan on keeping the truck, I would do it every 3000 miles.
