Really I think a 5.3 thats roughly 375hp is pretty impressive compared to the outgoing 5.3 and we all know how well they responded to mods so I would place judgement just yet.

The 5.3 in the COPO is a lsx block that's a big bore/small stroke as where the truck 5.3 is a small bore/long strong and is limited to smaller valves.

- Think roughly "current power-to-weight"...which should equal great performance combined with great mpg, a necessary component to any business case.

"Cost of manufacture" seldom/never is a guarantee of "selling price". What IS a guarantee is, with mandated systems, necessary fuel economy regulations, and supposed weight decreases inherent in next-Gen vehicles partially due to more expensive high-tech materiale, the only way to keep MSRP under some constraint is to "give" on some things. A 35-3600 lb Gen-6 Camaro SS will NOT "need" 450+ hp. Under 400 will deliver performance a Gen-5 Camaro owner will be able to accept, and retain their perma-grin. Detuning a 6.2 to less than 400 is simply dumb (or directly using the dreaded TRUCK version!) and would not adequately address the mpg situation. A 5.3 will...
Or would y'all prefer a V6 SS instead?

I would rather have a 5.3 over a tt v6 soley based on the sound that comes with it in a car like the corvette but the car did start life with a inline 6 so a "tt blue flame 6" could be cool to. Also I think that the amount of vette drivers turned of by the "lesser" 5.3 v8 would pale in comparison to the people that could now afford a vette if it comes at a lower price point.
