My wife and I wanted to say thanks to everyone for the excellent push of information here on the forums. Today, we took the first step to make it official. Months ago, Theta touched on the subject early on for us when it comes to forged internals for our car. Happy to report that we're taking the next step. In roughly 3 weeks, I will have secured my funding for our car to be stripped down in October. I've already got the parts listed above installed on our C7. Here is a brief summary of the new items to be installed:
TS&P VVT-1 Camshaft (with larger 33% fuel lobe)
TS&P Hardened Chromoly Pushrods
DOD Delete Kit (DOD hole plug, head gaskets, ARP head stud kit, lifter tray and lifters)
Comp Cam Phaser Block
PRC .650" Dual valve springs (including titanium retainers, hardened spring set and new valve seals)
CNC machine port our heads and hone the block
Custom Tune
Circle D PRO III 3200 rpm Torque Converter
Forged Wiseco Pistons and new rings (compression lowered to approximately 9.5 - 10:1)
ECS pulley (bought two different sized ECS pulley's to play with)

OK.. it's official. Baily's Hyperformance Factory took possession of our C7 yesterday evening. After speaking with Chris @ Baily's and Julio from Alky Control, I stepped up to a dual nozzle meth setup. I also spoke with the awesome guys at ECS when I purchased my extra pulley's. Shooting for 13-14 pounds of boost and my latest RWHP estimates should land me solidly in the 800+ RWHP arena. Yay, forged internals.. We're pretty excited.

Awesome. Keep us posted on the build. What's the time estimate?

About three weeks, give or take. SEMA threw us a small curve ball but I think all of the logistics have been worked out.
Another side note.. the day before we dropped off our C7 at Baily's, I scratched up the front Z06 stage 1 splitter on our car while parking . It can be repaired (it's painted carbon flash metallic) but for me, the cost would be the same if I just went ahead and purchased a new one. So, I purchased two more brand new replacement Z06 stage 1 splitters and they are currently being painted at Bruce Lowrie Chevrolet in Fort Worth. One will go on the car and the other will be kept as a spare (because I am sure it will happen again). I will probably just give the damaged one away and let someone who can do paint and body work, work their magic on it.

C7 LT1 Motor Limit?
I'm hoping some of the big hitters who own C7 LT1's can chime in with their thoughts.. I know fuel will be one issue on the stock pump (even with a 33% increased fuel lobe on the cam + dual nozzle 100% methanol alky control). Any other issues with 800+ rwhp LT1 Stingrays? Transmission? Axles? Output shaft?
I've upgraded the torque converter (Circle D Pro III 3200). For the M7's owners, any suggestions?

Yea you're not going to get to that kind of power with E85 and the stock fuel system. The low pressure side has to be upgraded as well as the high pressure side with a cam or LT4 setup (or both)
Good recipe:
headers
cam
blower at 10 psi
meth
700-750 to the tire and safe
Anything over I would be thinking a built short block and upgraded fuel system to not have to rely on the meth.

Just purchased the Borla ATAK exhaust system a few minutes ago. I spoke with Steve at Borla for a full 30 minutes on the BEST system for my particular setup. He recommended this system for my build. That officially means that no part of my exhaust will be factory..

I think Vengeance just did a car making 850whp on stock shortblock/heads with cam, ecs 1500 @14 psi, and dual nozzle meth.
You can get away with a lot more power if the fuel is up to snuff. Meth helps a lot.

@ Ninjaman51 ...if you want the splitter, we will part with it at no cost.. All we ask is you pay for the shipping. Just warning ya, it can be a bit expensive.

Just a small update. Hopefully, we will get our car back in the next 10 days or so. Baily's Hyperformance dropped all of the suspension, exhaust system, trans, torque tube and engine. The only thing left was the "shell" of the car. The Circle D 3000-3200 stall was installed and I believe our Borla Atak exhaust was being prepped for install as well. As far as I know, everything was reinstalled minus the engine / front suspension.
We were waiting on the heads to be finished. It's getting close to getting our car back up and going. We bought the Borla Atak cat-back Z06 exhaust (P/N - 11869) and took it locally to Specialized Performance Coatings to be professionally ceramic coated BLACK. We haven't forgotten the wheels and tires. We purchased the non-run flat Michelin PSS's (255 35 19's up front and 295 30 20's in the rear). Those will be mounted on a brand new set of Vertini RF1.1's (19x9.5's fronts, 20x11's rears). It's almost like an early Christmas present.. LOL!

Just out of curiosity, why did you get like the smallest tires that fit your new, wider wheels? You could've easily gone to 275 fronts and 305 rears with those wheels still in the MPSS tire. Or gone with sticker tires because I know you have a pretty strong build. I just feel like you still won't be able to get much traction with that set up. (You are supercharged if I remember correctly?)
#1 - Price to performance ratio. What % of "improvement" will I gain going from a 255 to a 275 & going from a 295 to a 305? Not much at all (if any in real world numbers). But financially, the cost of making that jump would not be worth it to us.
#2 - Form and function. We don't plan on drag racing our car at the local 1/8 or 1/4 mile track each week. Will we dabble from time to time? Probably just a bit. But at the end of the day, it's just a good ole fashioned American sports car. Our focus is to keep it as such. We could have gone with stickier rubber and wider tires (again, the cost to maintain that setup would be much higher). At roughly 800 - 850 rwhp, there isn't really too many tires out there that I know of that would make a good all around tire (all weather tire / street tire / 15,000 - 20,000 mile tire).
#3 - This is probably THE most important of all. Being happy. We are happy with the way our car is. One day, maybe we will get tired of having "295's" in the rear and just go full on crazy by removing the rear ducts and throwing on some "375's" ..But, at the moment, it's not our focus. We are content with a modest looking Stingray, a few aftermarket exterior styling parts, a nice set of wheels, a sexy exhaust note and a tiny 900-1000 crank hp engine. Hehehehe.

Hah... Modest looking stingray... Your car is beautiful and is a huge inspiration. And that engine... Mmm. Thanks for the very appropriate and thought out answer! Definitely makes sense from that point of view.
