So I have a 2015 Camaro ss I have a fully built procharged ls3 in it making just shy of 1000whp just got done being built and was wondering what to do with my transmission the 6l80?
I’d like options/opinions on whether I should build that transmission or just swap it for something else?
I would like to still be able to street drive it and maybe take it to near by towns!

Theres a good amount of options.

Build your 6L80
Build a 4L80
Go with a ZL1/CTSV 6L90
TH400
Theres wiring harness now that allows for a plug and play 10L80/10L90.

Really dependa on what you want to do with the car. Dedicated drag car i say TH400. Budget mindful build your 6L80 or go with a 6L90. Unlimited budget street car build a 10L90 and do the harmess.
