We talking TT, I assume? Considering that's what was posted, and that would be the most comparable, I'd think (boosted, big aftermarket, highest performance). I really don't see it being close, considering the TT is less than 50 pounds lighter than the LS1 (apples-to-apples comparisons on this are hard to get), and the Ecotec is all aluminum like the LS1, but less than half the size.
