The difference is the bore diameter, so if you've got a head off you can measure it. A 350 has a 4" bore, a 305 is 3.75".
Another possibility is to write down the letters and numbers on the identification pad just in front of the right-side cylinder head and go to this website to trace it: http://www.nastyz28.com/chevy-engine-code-stampings.php

Can a TPI set up and computer from a 305 TPI be used with a 350 block and heads?
Yes it does work. However you will also need to use the 22 lb injectors for the 350. To get the full benefits from the upgrade you should get a 350 chip burned. The computers are the same but the chips are different. This is all considering if the swap is for a lb9 (305) to a l98 (350).
