Budget 4l80e build

OK I've read that a stock 99+ can take anywhere from 550-700 horse. I've got a guy looking for a junkyard 80 for me and told him to get it if he could get a good deal on it. I plan on doing a rebuild/refresh with a TCI master racing kit (Red Eagle clutches, Kolene steels), and TG HD2 shift kit. What are the weak points that I will want to also address? I already know what I gotta do on the older ones, but anything else? I wanna be in the 700+ range with the small upgrade. Thanks for the help in advance and don't be a troll.

You shouldn't have to do anything else IMO, But I'm not a sponsor trying to make money either.
Just make sure the clutch clearances are good. Don't re-use the spring steel cushion plates, use the old th400 style or at the least get new ones.

I wouldn't use the Kolene steels either. I'd just sand the stock ones.

Also 97 up trans have a smooth rear band which is great on the band surface but as soon as it glazes it is done so dont have the rear band to loose where the servo will run out of travel and destroy it. the 4l80-e intermidiate sprag is already the better cam type but you can buy the 36 or 38 element sprag for additional strength.
