First thing out of the way. With those goals on the 6L80e, you are going to absolutely have to beef that transmission up (and supporting mods). Without that, the rest of this will be pointless. That stock trans will not tolerate those power levels, especially under any kind of abuse (racing), for very long. The 6L80e can be built very strong and reliable for whatever power level you desire, but money is always the deciding factor. Others prefer to swap out to the robust TH400, but there are of course sacrifices going that route.

I am only around 460-470 rwhp, but I can already tell my transmission is getting kind of tired and lazy. I haven't even installed my new stall convertor yet, so that has me nervous...especially at 174k miles lol.

You are also going to want some rear end mods as well to be able to put that kind of power down without breaking things due to know wheel hop issues on this platform. Trailing arms, toe rods, LCAs, and would also recommend cradle/diff bushings. Rear axles, diff strengthening or replacement...it's never ending. There is plenty more you can, and will likely have to do, but these are a few that jump out at me right off the bat based on your goals.

But most importantly, welcome to Camaro5!
