If you want to hang with the newer cars and get the most out of your car the first question is your 02 TA an automatic or a stick?
A high quality torque converter (Vigilante, Yank, Circle D) will do more for an automatic transmission 02 TA than a cam swap.
Given the car has a 6.0, headers, cam of some sort & was tuned, that should make a very good starting point. How are the tires on the car? Good tires are as much safety as performance. Check the date codes, check for cracks & condition etc.
Can you share a few pictures of your 02 TA with us?

Sweet looking T/A, like the wheels and 295's!
FWIW - 233/248 111.5 LSA cam has 17.5 degrees of overlap. That's pretty rough driveability wise by many peoples standards with a stock driveline. Not talking about inexperienced folks that have never had a hot rod.
Definitely need an aftermarket torque converter for you to get the benefits of that cam. Something like a Yank 3600SS or Vigilante 3,500 and 3.42's or 3.73's would probably work pretty well.
Does miles per gallon matter?

I have a 2002 Pontiac trans am and recently found out that it has a 6.0 in it. I’m pretty sure it is a lq4 or lq9. it’s already cammed but it’s not enough for me. I want to replace the cam myself but I do not understand any of the terminology of it. I’m thinking of replacing it with a stage 4 cam but I have no idea what to look for. The engine is also running with 799 heads. Can anyone tell me which cam to get that is a stage 4 and the pushrods and springs I need as well? Please and thank you!!
Just ditch the LS based bullshit. Nobody has ever made power with that crap. You need a 4 rotor Wankel for real power. The bonus is that those don't need cams, so you will not have to bother us with stupid ******* questions like this ever again. Or you could do some research. Whatever you think is best.
On the other hand, can you imagine a 4 rotor wankel at about 60 or 70lbs of boost in almost any rear wheel drive car? Total smackdown until you get charged with murder when the apex seals fly threw the loser's forehead.
You've completely missed the point. I used the BTR stage 4 cam specs to calculate the over lap so you could see its has 17.5 degrees of overlap which is pretty rowdy to deal with in a driver. Probably want to see, hopefully ride in a car in real life with a similar cam before committing.
If I was going to use a very aggressive cam with ~17 degrees of over lap. I like this one:
