Most Haynes manuals now have this info in the back of the book. I am also assuming that the O.E. sticker that shows this info under the hood is missing?

Adjust timing 1989 Pontiac Firebird Formula 350

To get at some of the bolts to loosen you need a special wrench that looks like a large square c. this consist of the handle end and the box end that goes on the bolt. First take a flashlight and look at the bottom of the distributor, the thing with the 8 spark plug wires and cap on it. You shouls see a small bolt with either a 1/2 inch head or 13 or 14 millimeter head. rare is it smaller then these 3 suggestions.carefully loosen the bolt a little so you can move the dist by turning it. Do this without the engine running. If you have a timing light you need to clip on your #1 spark plug wire. I not the old fashion way is to start the car and rev up the engine to about 1500 rpm or 1800 and the rotate the dist left and right until you gets the engine where it runs its best and then back it off a hair,have someone with you and have them remove their foot off the gas and then shut the car off. re tighten the bolt carefully and then restart and see hoe she runs. This method works very well, in most cases you should be within 5 degrees of correct timing. On some models with extra vacuum lines it may be off a little more...Until you can have someone else check it this can work in most cases..
