1968 Pontiac Firebird

[cully]

I have a '68 Bird that I have owned since 1968.  It has been sitting in the garage for more years than I care to think about.  I am starting to restore it and would like to change the carb from the stock 2-bbl Rochester to a 4-bbl Rochester and would like to know if it's possible to find one from 68?  If so, is there a certain part number that I can look for.  Thanks--Cully
