Hi everyone, Looking for another spare 1972 Buick 350 Quadrajet in case my "rebuilt" one does not work out. Is a 1973 Buick 350 Quadrajet the same as a 1972? If not, what are the differences? I'm looking at the following auction on ebay: http://cgi.ebay.com/ebaymotors/Rebu...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
