The LS3 is used in the base model Vette, not the Z06.
The LS7 is alloy block, same as 1UZ, so its just as light, and each one is hand built. So its 'primitive' just because it has pushrods? Big deal... It's putting out the kind of power you need to supercharge a 1uz to make... and thats standard without any further tuning. If you want to go nuts, go the LS9.
As for this power per litre argument, again... its a retarded argument... power per litre is irrelevant, an S2000 motor pulls more power per litre than a 1UZ... yet put one of those in a Soarer and tell me how it goes?
Correcting my comment above about powertrain, I just remembered the latest vettes run a transaxle setup, so it makes sense to upgrade the whole drivetrain if you want to go down that path... but as to why you'd bother wasting all that time, effort, and money on a Soarer is absolutely beyond me (yes, shock horror - these vehicles are not as good as some of you may let yourselves believe, resale figures and demand for them on the market confirm this ugly truth)
