GM offered the Z51 for those that wanted to track their C6 from 2005 through 2009. Then GM offered the Grand Sport which is the Z51 option, but on steroids. If those that tracked their Z51, then they will most likely also track their Grand Sport. The dry sump engine is just part of the package that makes the Grand Sport track worthy.
Sure, not everyone will track their Grand Sport, but neither do all the owners of Z06's and ZR1's.
Nice thing is that if you don't want a particular option on your car, then don't check that box. But those that do want a particular option, they can check the box and get it.
Funny how life works.

Bottom line, buy a Corvette with Y option, not X option. Like I did.
Everything else is wrong.

Coming from a mechanical background.(ASE certified) I'm impressed by the fact America still actually puts things together buy hand in a manufacturing process.Im curious if it's Ferrari hype also.Love the fact that my LS7 is hand assembled by the fine UAW technicians of wixum.

OregonC6+1. One thing we can agree on is everyone has an opinion. I am on Corvette No 4 and based on my experience the less complicated and simpler I keep my Corvette the less problems I have. I think oil sump is a very sweet option to have but the key word is option. There are a number of post about problems just getting the oil changed with the oil sump system. Not with the system just the idiots doing the work. To each his on.

You also get the forged crank on the hand built only.
I would rather have a person push my pistons in the block as opposed to the machine pushing them in. Hand built also gives more attention to the rotating friction that the production built engines.

That settles it. I'm having a Dry Sump badge made for my GS. 
Seriously, there's no shortage of instances spoken of on this forum of C6's blowing it up on the track due to oil starvation. Dry Sump is your friend if you track it.

Yes, and after reading a lot of posts on the subject I've concluded that at least 95% and perhaps more of these "hand built" manual trans GSs will not be driven in a manner ( on tracks ) that require this oiling system.
The dry sump adds complexity ( not a good thing unless there is a reason for it ) and weight.
The primary purpose of the dry sump system ( IMO ) on the GS is to make it appear more like the Z06. Given the reliability of the LS7 that should be the last thing any GS owner would want.
The dry sump system is all about bragging rights about something you don't really need anyway. Or perhaps I missed something........
It's a solution for a nonexistent problem for most owners of the manual GS.
As for "hand built" this also is all marketing hype. As anyone knows who has looked into it even superficially the so-called hand built engines are assembled mostly by one person vs , apparently, more than one person in the normal manner.
However, it's clear that all parts are right out of the bin the same parts used for the non hand built engines. None of the parts are weighed, matched, balanced, or undergo additional inspection.
All the engines are "hand built". You thing maybe the special LS3s get more personal attention get a load of the torquing fixture that tightens and confirms all the bolts on the head in one operation. Probably the same fixture they use on the non-hand built engines.
It's all marketing and it's been brilliant. They have , without ever saying it, convinced thousands of buyers that they are essentially getting a balanced and blueprinted custom engine when the fact is they are not. It makes the same power and it has the same reliability (unless someone can point to reliable statistics that suggest otherwise ).
You pay more money for a hand built engine and you are not paying for higher performance or reliability you are paying for bragging rights to something that really doesn't matter at all.
just my opinion, I cannot believe so many people put so much credence in this entire hand built thing....that is what is amazing.

Yup, only manual GS coupes have them. That means the convertible GS's don't. They have the paper mache cranks.

Just because a hand built engine does not produce more horsepower, that does not mean it does not have advantages.
If you did some research you would find that you are incorrect, there are advantages to having it built by one person, but I guess are the type of person that when they hear something they want to believe, they spread it like gospel whether its true or not.

Location of Engine Builder on GS Engine?
Can someone tell me where on the engine I can find the name of the person who built my engine? Before someone asks, I have a 2011 GS 6M.
Thanks.

this is from a previous thread on the topic.
"Each engine has a builder ID tag on the front surface of the intake manifold (IAFM), on the RH side."
