Hey CMsecretary, your info is not 100% correct -- you are the one who needs to read up on cars. Sometimes a bit of personal experience does not give you COMPLETE knowledge about a subject! I had a couple of eighties Z-28s and guess what? Both had 305s in them stock!! Oh, and you can start your studying-up right here on this forum by reading the section on Z-28s. Most later eighties Z-28s came with 305s not 350s! I know this because when I went to look for my third one I had to look at a lot of cars before I found what I wanted -- and even then it was not a Z-28, but an '88 T/A GTA with the TPI 350. T/As also mostly came with 305s.
Again, if you want to add something make sure it is correct info. It is not foolish to not know something -- but it is foolish to think you know it all when it is obvious you don't!
