Welcome aboard thirdgen.org.
First, I moved this from the "Pontiac V8 Swap" sticky because your question isn't what that thread is about. You have a small block Chevy in your car, not a Pontiac V8. If that revelation causes you some psychological damage, well, sorry, sometimes the truth hurts.
Now, what all of the "350 TPI" did you get? Engine, TPI hardware, harness, sensors, ECM, fuel pump, throttle cables - hopefully you got all of that, or can go back and get it. With all that in hand, remove the 305 and TBI stuff, and put the above 350 and TPI stuff in.
What did the 350 TPI come out of?

Re: 305 TBI to 350 TPI
There is a tech article on this website on the main website page that details the TBI to TPI swap. There are also hundreds of posts from members who have done the swap that you can 
and read and learn. Good luck!
