So far I'm satisfied with the overall performance of the car. This is my 1st LT1 so I'm comparing it to the ZZ series engines and backyard built small blocks. It's getting about 23.5 to 24+ MPG so far which is kind of impressive to me after driving the older engines. Could be because I do use 6th gear OD a lot and don't push the car too hard. That said it sure will pass the Blue Hairs in Buicks who always manage get in front of me going 37 mph on the open road. Time will tell.

Hows that 3.8 perform? I've heard stories that those are pretty amazing engines.
