I am not sure which manual you have by gm but, I have the 1985 pontiac firebird service manual and I believe the information you want is in the Driveability And Emissions Carbureted section. It only covers the 5.0 vin code H,G,F.
There should be a camaro version.

You can also get Chilton's manual 8534 for the pontiac firebird and go to section 4-72

Hopes this helps
