Wow - that for sure was about to become a real bad day. Was that the installed lifter at delivery or GM's 'Race' lifter?
Hard to believe that GM would use a lifter with a u-clip style retainer in a high performance application.
Thanks a mill for the "heads up"

I believe that was a standard ls7 lifter that had failed. Again just my .02 but just the build of the Johnson lifters seem better. The roller tip seems smoother and more robust. It also uses a high quality c clip retaining the plunger vs the u clip. I don’t have any 1st hand experience with the “race lifters.” My comparisons are between the ls7 and Johnson lifters.

I hate to be the bearer of bad news...but if you've got an expensive to repair problem - as I did with the Auto Transmission's slippage - GM can decide to void your warrantee anytime they feel like it for replacing things like the spark plugs or anything else with a non-deco part-number. The other side of the nightmare that I think happened to me and brought to light by the knowledge of a couple of forum members: The dealer will over-state things to GM - like things that you have changed (like installing Magna-Core spark plugs) - I'm not kidding.
Why - because they lose money changing out a transmission as GM pays them a fraction of what they would have charged a customer for parts and labor. So things at the dealerships are tough and why should they lose money working on your car? So they come up with all sorts of hot-button issues that they pass on the GM so GM ends up voiding you driveline coverage. Stupid **** like your after-market air-cleaner, intake tube and a ported throttle body or how about your X-pipe or aftermarket mufflers?
Don't think for a minute that they can't/won't do it. Your only alternative is to sue both the dealer and and GM. In my case I've got a documented Lemon-Law claim. So what do I do when I win it? There are no replacement ZR1's and the odds are very long in getting the court to replace my ZR with a C8 XR1 when they are available. Things are so tight at GM they wont even implement a design change to the transmission and fix the damned transmission even though they knew they had a big problem with it on the C7-ZO6,s. And guess what...they are still putting this transmission on the Cadillac and history is repeating itself there.
Since you are closer to Florida than you are to Texas and Arizona, and you do decide you want more power, I'd suggest that you include getting a bid from Redline Motorsports in Pompano Beach, Florida, Howard Tanner's operation. They moved their operation from New York where Redline used to be located several years ago. Tanner used to work at GM and the only thing he works on are GM products. In addition to installing his 3rd party torque converter that has been race-proved to be the fix for numerous Z06's and Cadillacs.
In addition to buying the HP tuners "crack", I'm going for a streetable 3/4 cam and a bunch of upper and several lower end improvements that just make common sense.
I dont give a damn about the car's resale value. That window pretty much closed when I passed the 10,000 mile mark.

There was a judgement against Harley Davidson recently for doing these very things. This could be the start of turning things around. Being a federal decision, who knows

Next time I chat "off the clock" with a good friend attorney I'll run this past him. No question, according to the "experts" I've consulted, that GM would lose a lemon law action - but where does that get you if they are not making the car any more?
I'm waiting for the parts to appear that are required to repair the transmission slip/shudder. When they show up at the shop and they can block the consecutive days needed for all the work to be done in one visit, I'll drive the ZR to the shop for it's new end-to-end ARH long-tubes and it's Stage 3 transformation. Then I'm gonna set up another IMRA high-speed aerodynamic test so we'll see what it does to my standing mile and top end speeds. And yes, on the tune, we are also going to bump up the max speed nanny just for grins and giggles.

Yo Mopar... Yup, you are probably right. but It all depends on the buyer doesn't it?
I've seen lots of modified Corvettes sell for big bucks at the auction too. If I was looking for making big bucks reselling it I should probably stop driving it too and keep the miles as low as possible. I bought the car to have fun and go fast and not as some long term investment.

Car cannot put the stock power down. Whats the point of adding more power to it? There are very few times I can go WOT in 2nd gear and almost never above 70% throttle corner exit. Ignore my post if all you do is mexico racing in which case I can see 60-130 times improving.
