305 To 350?
I have just recently bought a chevy 350 block with a edelbrock complete setup on it. 650 cfm performer carb ect. i now also have a shot to get an entire late 80s Z28 with the 305 and the TPI for free. im using it for the rear end and some other misc parts. i was thinking that putting the TPI unit on my 350 engine would mean an increase in horsepower as well as some fuel econ. How much work / cash would it take to convert the TPI from 305 to 350?

Welcome to thirdgen.org.
I'll leave the HP thing alone...
All you'll need to do to make it like GM did, is change injectors(from 19 to 22lb/hr) and knock sensor (for a 350) and run a eprom for a 350.
Other than a gasket set, you'll be good to go.
