Several individuals and companies will port/polish and even bore out your stock TBI for a fair price. Or you could do those yourself.
(See Ultimate TBI mods)

You could also look into
a TBI with 2" bores from a BBC or an aftermaket unit from Holley.

They sell on Ebay all the time
thirdgen's classified section is a good source as well

The TBI unit is not really the biggest bottle neck on the car.

It's all in the tech articles. Do a search too. Much can be learned that way.
