4l80e in a Z06. Who has done it or wants to do it.

The entire drivetrain needs to be modified. If you don't deal with corvettes it is hard to imagine that much could be required to do the job. I'll start from the engine and work my way back.
SFI Flexplate
SFI Torque tube coupler
SFI Bellhousing
ARP Flexplate bolts
Automatic torque tube
Labor to shorten the torque tube
Custom length propshaft for 1000hp
High performance propshaft couplers
SFI Converter drive plate
Custom built 4L80e converter spec'd to the customers application
Built 4L80e transmission
Labor to machine the transmission case to fit into the Corvette
Custom billet adapter plates to adapt the 4L80e to the corvette torque tube and Z06 differential
Custom 300M billet output shaft to fit into the C6 Z06 differential
Custom differential brace to strengthen the trans to differential connection
Stand alone transmission controller, wiring harness and neutral safety switch with wiring
Trans cooler and cooler lines
Normally the builds include differential upgrades as well because if the car needs a 4L80e it normally needs some upgrades.

Just a tame 4L80E build would be $3K in a standard car/truck.
Show them a picture of what the 4L80E looks like after the conversion is done. I know Howard at Redline had one out last I was there.
I specialize in 4L80E's. I could easily make the adapters, braces, machine the parts but I would invest $10-15K in tooling and time to make ONE set.
Does anybody here own their own CNC machine? If not and if you don't know how to use Autocad or Solidworks to draw the parts accurately, you're not just going to "make it happen".
$15K is a fair price for that conversion.
Most enthusiasts have no idea the time it takes to deal with conversions and all the "catch me/f*ck me's" that cost unpaid time.
My pricing will be increasing 10% across the board in September to offset some of that type of hassle.

I spent about $11k to do my RPM 4l60E swap into my 02 Z06. That was with a level 7 trans all all of the drive train upgrades... That was doing all of the work myself.... No doubt an 80e will cost a ton more... There is a lot of machining that has to be done to the 80e case, not to mention cutting the **** out of the floor pans.
Unless youre gonna make well over 900rwhp, I'd stick with the 60e, but ONLY an RPM level 7.

The case is the easy part, you "could" do it with a sawzall and grinder. We mill the bellhousings off on the 4L80E's that we convert to other applications.
The custom made low production output shaft, and the CNC'd adapters required on BOTH ends of the trans are where you are paying RPM for their development time.
I have several cases milled here now, one for a Toyota Supra application and another for our in house conversions to use a SFI bell behind Mopar, Ford, and other popular applications.
Another point,
The Supra we have here has a CNC'd adapter from another vendor (not on this forum) that is not correctly machined. So it's eating pump bushings, converters hubs, and front seals. That customer is paying $100/hr for me to determine the cause and correct it. I have to machine parts to check centerline of each piece (pump, adapter, Toyota bellhousing) to find where the problem lies. THEN we will have to machine a new adapter more than likely. One off piece will cost a couple of thousand.
It's MUCH easier to do it right the first time.

They have to make this (4L80E, note 1-piece integral case and bell housing):
fit like this (4L60E, note stubby bell housing and differential case directly attached):
( I apologize for the huge size, I borrowed images from Google )

Maddog Lou Hopefully next year sometime I will buy the kit and build my own 4L80E. C-6 Z06 1034 RWHP. Running a RPM 6 speed manual don't really get involved in high performance manual transmissions. Very knowledgeable guys at RPM. My car was built by vengeance racing and I drive it hard everyday.
Thank You,
