Not sure on Eastbaycamaro's power level, but what are your thoughts on even attempting to use a 4L80E with $10k worth of parts on a heavy 3800 lb 4th gen that will see 1500 rwhp?
Something just tells me:
"no don't even bother... it won't hold, go with RMVB transbrake TH400 with that money instead and slap on some 3.25's and 28" tires."

Did you mean 4l60e?
Because getting a 4l80e to support 1500hp Can and HAS been done for far less than 10k built with a warranty. Which means there's nowhere near that much in hard parts.
This thread has gotten out of hand.
I've supplied the names of multiple vendors for both the transmission and the torque converter.
Call them and detail your setup and ask their recommendation/pricing/lead time.
there is an abundance of parts (most developed for the th400 that will directly interchange with the 80e) out there that will happily support 1500hp. The weak link becomes the overdrive roller clutch...stock has been pushed past 1500hp and it's usually the splines that strip...so there is an aftermarket option for that now.

4l80e with 10k in parts...um no. That doesn't make any sense.

I think he meant the car / engine has 10,000 worth of parts

Are you saying you have 10K in the car, or in the engine, or in a 4L80E transmission???
Like Marooney said... I don't see that Kind of money spent on parts for the 4L80E normally.
3,800 Lbs is not actually heavy for a street vehicle... Some of the builders actually rate there units power capabilities for trucks (around 6,000 Lbs).
I personally much prefer the 4L80E for anything in the 1,800 HP range and down.
I then usually go to building a THM400 for street vehicles and a TWO-speed THM400 past that point for track only vehicles. (Power-Glides also end up in that Mix at times too).

They tolerate a HOT transmission and work fine for a track only application... But who teaches all these guys that "Magical clutches" exist???
Well not quite $10k, but an RPM level IV is $7000 with the gear upgrade and I’ve heard from several reputable speed shops that a built 4l80E has issues when you get into the higher hp applications of over 1000 rwhp and to go with a TH400 or a glide.
I’d love to get a 4l80e and enjoy that over drive gear on the highway, but I was advised to just deal with the TH400 or get a glide with gear vendors at that power level.
Here’s a good deal on a 4l80e setup

RPM seems to have a good reputation going. I am not familiar personally with their units to say with any certainty. I'm sure one of the builders here has at least had a peek inside.
To my hearts sadness, my wallets happiness and my brains complete lack of understanding... Transmission built for 1,000+ HP is considered by too many builders to be a "Specialty".
Many builders who do not understand their products and simply build them without any thought process will say that something is not possible or that problems arise.
This is not true in regard to the 4L80E units with 1,000 HP driving them. Many of us build them to double that horse power with out issue.
If those other shops wish to call what I do a "specialty" and farm out the work to me... It is fine by me.
What I do not like, is lying to customers and stating that "it is not possible or is problematic" just because that business can not do, what I and many others do.

For only 1,000 HP... I would build the engine for 600+ HP normally aspirated and go with a single turbo-charger instead of two.
Do not start looking at camshafts yet until you have the cylinder heads and much much more planned out for the engine...
I am very fond of the Y-Block LS Next Aluminum cylinder blocks (not the blocks with the deep skirts removed) and have two of them for myself.
There are many aspects incorporated in this cylinder block that I prefer over any of the production castings.
However for low power production... It is too expensive in my opinion... If you have a ton of $$$ then go for it! It's Awesome!
Sorry... New Engine Thread Please... and drop a hyperlink... do not continue here... Thank you :-)

And.....just hooking up the plug-n-play 60E-to-80E harness........it was almost ready to go. It just needed some personal tweaking that we did. But my 1998 PCM operated it just fine without doing anything at all. But after tweaking it was spot on with all the line pressures and shift points of course.......

5k for an 80E is the real crime here. Get yourself a bucket, old flexplate, and stand that unit up, go to harbor freight and get yourself some pics for about $5, a piston compressor, buy the necessary hard parts.... and go to town. And whatever you don't know, come here and ask. A weekend, and a few six packs later, you'll have 5k worth of transmission, for maybe $1k, if not less.

If I built it...it might fall apart.....lol
