I know this sounds like a dumb question but I need to know how much oil the '85 Z na's required. I'm doing a rebuild petty much of the entire car so I don't have any of the owners manuals or anything. I just figure it'll be 5 quarts but not too sure. Thanks.

Dude, car shops will be able to tell you instantly. They have their own manuals and books.

well that kind of takes the fun out of the forum doesn't it?
