1985 350 tpi into a 91 firebird with a 305 tbi
The main reason im concerned is I live in california I have to have the 350 tpi be able to hook up to the smog on the 91 and I don't think I can do it without finding a 1991 350 tpi .............. any help would be appreciated I tried to do a search

Technically, you'd need a speed density TPI, since that's what the '91 year model had for TPI. It wouldn't have to be a 350 TPI, as long as you had the computer tuned for 350.
You will need dual cats, because that's all the '91 350's had.
You could put the 350 under the TPI, because the B-body cars had 350 TBIs.
