Rebuilding 350, what topend?
I am currently rebuilding a chevy 350 to put into my 86 Firebird (which has a 305 TPI currently) I already have a Comp Roller Cam, Lifters, and Pushrods. I am still not sure on what will work better HP wise. TunePortInjection or Carb....i have also looked into a blower. Please let me know what your thoughts are, i am going for a budget horse power, so please any comments.

Its simple TPI is not a performance induction system, it never was meant to be and never will be. You will instantly make more hp going with a carb.

...which may instantly put your car on the trailer, designated as "off-road use only" if you have emissions inspection/testing in your area (technically, by Federal law, that's what you would be doing, anyway).

you'll get so many different reactions from so many different people on this one. You have the cubes, but none of the goodies, basically saying "build me something" lol.
I dont know what horsepower range you want in, or what RPM band you want... but if you want to keep with fuel injection, and are on a budget, get a LT1 intake
I'm very fond of them.
