You can clearly see the centerline of the transmission and it's input shaft sits ABOVE the flanges of the half shafts of the diff on the transaxle. Unlike the C7 transaxle where the diff sits behind the transmission, the entire center line is lined up with the center of the flywheel. So ANYONE intimating that the LT2 sits lower in a car than the LT1 is, yes...

LYING.

If your source that says the LT2 sits lower than the LT1 is the chief engineer of the Corvette, Tadge Juechter, then that's an unequivocal YES. Not that he "lies," but you have to read between the lines in everything he says, because he's an active spokesperson for the Corvette program and frankly, parses everything he says. If you're active on the Corvette Forum, he actually has a "Ask Tadge" forum and while he did not have to participate, he does, and the more you read the more you realize that everything he says to the public is designed to be said to the public, and most of the time certain detail is omitted in the way he phrases it so that there's enough ambiguity that you can't call him out for an out-right lie.

A statement such as "the new LT2 in the C8 has a lower center of gravity than the LT1" has a crucial detail omitted.

Which LT1 in which car.

If you don't do your own research, and understand how things work, you can easily read that to imply the LT2 sits lower than the LT1 IN THE CORVETTE C7. But that's not what he said. The LT2 sits lower than the LT1. Without implication, that can mean the LT2 sits lower than all LT1, or sits lower than the LT1 in the CAMARO. Which it does.

Based on the information I've provided, the fact that the dry-sump equipped LT1 in the C7 sits on the same plane as the transaxle and has the exhaust manifolds yield DOWN rather than up, do you REALLY think that the LT2 in the C8 sits much lower than the LT1 in the C7? And if you do, is that purely based on TJ's saying that it does, without implying that it's the LT1 in the C7? Because the CENTERLINE of the output half shafts on the C8 already sits 1" higher than the centerline of the output half shafts on the C7 (the rear tires are 2" taller in diameter in the C8), and the flywheel on the LT2 in the C8 would sit another 2" higher than that based on the diagram of the DCT transaxle.

So you tell me how it is possible that the LT2, which has basically the same block, but one more cam shaft, and an exhaust that routes UP instead of down, has a lower center of gravity than the LT1 as equipped in the C7.

The ONLY thing I will concede, is I've actually never read where TJ or any of the engineers imply that the LT2 in the C8 has 2" lower center of gravity than the LT1 in the C7. I don't know if the statement is as cut and dry as "LT2 sits 2" lower than the LT1" or if they implied that the actual center of gravity in the C8 is lower by a couple of inches over the C7 (entirely possible as a package).

All I know is it's highly unlikely that the actual LT2's center of gravity as mounted in the C8 is actually several inches LOWER than the LT1's center of gravity as mounted in the C7. If you use the main crank pulley as where the centerline of the crank shaft is, and by relation where it mates and mounts up to the DCT transaxles are, by comparison the LT2 can't POSSIBLY mount lower on the C8 chassis than the LT1 in the C7.
