I think we need more information about your V8. Basically speaking, your V6 computer won't work (at least without modification), and the wiring won't work without major rework.
If your V8 is a computer controlled variety (CC carb, TBI, TPI), then you will need a computer and the harness to go with the engine.
If you are eliminating computer control via a mechanical carb and vacuum/mechanical advance distributor, then you just let the computer go along for the ride. It doesn't hurt anything, your SES light will come on all the time but just take the bulb out, your TCC lockup (if auto) won't work anymore so you'll have to rig that up one way or another.
Give us more specifics, and we can give you more specifics.
Oh, the best thing to do with the V6 computer is to sell it and include the rest of the car in the deal. Take the proceeds and go out and buy a factory V8 car.

Well I only bought the car for $100 needing a motor and transmission, with a perfect body and rare options for a V6 Car such as Console Clock (1,995 produced), spoiler, Gauge package, and cruise control. Well I am gonna put in a non computer controlled carbureted 350. I have another Camaro thats wrecked and it came with a V8 and 5-speed(my car came with auto.) Could I put in that computer if I wanted to and make it work?

If the car was rare because of the options that came with it because it was a V6 (my V6 had cruise, BTW), putting a V8 into it will remove all of its collector value (if it truly has some).
You have me a little confused, but what I think you are saying is one option is a non-CC 350, the other is the V8 from the wrecked Camaro from which you would take all that's needed to get it working.
The non-CC question is answered in my first reply. The CC you have would work if you kept the T5 (sounds good to me), but would work except for the TCC lockup with an auto (you'd have to find that stuff from a different car). Harnesses could be spliced, but, sticks are more fun to drive anyway.
Economically, you practically have to get the V6 and V8 cars for free and do all the labor yourself to even come close to breaking even (vs. buying a factory V8 car to start with). But, there is some value in becoming very familiar with what makes your car tick by going through the V6 to V8 swap. Just don't plan on getting your money back out of it.
