Hello People! I am a newbe to this site. I was referred here by a question I had about intake castings. I have several early Z's and ZX's so I am trying to put together what years and models had what intake's on them. Now this only applies to the 75-83 fuel injected intakes. I would love to see If any of you have a break down of these. I am also trying to find out which years had the Idle air control in the Throttle body rather than on the side of the intake. Any help with these issues would be greatly appreciated. Thanks Josh
