Yes, the LSA got a bump moving from the CTS to Camaro but that was due to a more room in the Camaro, at least what I read.
How many variations of the 4.6 did they build? How many variations of the 5.0 have they built? How many engine changes did they make for the GT500?
When the Camaro was being killed off, did GM drop in the LS6 as a final farewell? No. You can't tell me the LS6 was that much more expensive than the LS1.
The LS3 in the Camaro is rated lower than the LS3 in the Corvette. The LS1 Camaros were rated way lower than the LS1 Corvettes even though they had essentially the same engine.
The LSA is nowhere near the LS9 in power output. When the GT500 came out with 662 hp, GM didn't do anything to the ZL1 to make it a little faster.
The only reason the Z/28 got the LS7 is because they had not other option.
As for Ford only having 444 hp N/A as of now, I bet the GT350 matches or beats the LS7. GM has completely given up on N/A engines for higher performance trims.

The way I look at it, Ford had to up the power on everything just to remain competitive. GM built the better car & therefore didn't need to play that game.
Why didn't GM drop the LS9 into the ZL1? The better question is: why would they? The GT500 is out of production anyways. But despite that, an LS9 Camaro would still be down 30 hp and be several hundred pounds heavier.
And I'm not sure why you are so down on the LS7. Its an absolutely awesome engine. Easily on anyones shortlist of greatest V8s ever built by a domestic automaker. I wouldn't want any other engine in the Z/28.
