If they claim the C8 LT2 sits 2 inches lower than the LT1 in the C7 with dry sump, I find that HARD to believe. IF they claim the LT2 has lower center of gravity compared to the LT1, I also find that hard to believe given the exhaust piping on the LT2 pipes UP vs down below the block on the LT1. In fact, the LT2 likely sits a few inches HIGHER than the LT1 due to the way the DCT transaxle is mounted (the LT1's driveshaft, torque tube, input and output shaft, and the diff's half shafts are all on the same plane. The LT2, due to the way the DCT transaxle is packaged, has the whole transmission/flywheel combo sit above the output half shafts of the diff).

Here's a good picture to demonstrate.



See the centerline of the transmission sits above the centerline of the half-shafts? That means, the center of the flywheel on the LT2 sits a few inches HIGHER than the center of the flywheel on the C7 LT1, because the transaxle on the C7 has the diff and it's output half shafts perfectly inline with the flywheel of the LT1.
Let's see.

Yes of course, the GM engineers are just making stuff up.
