Get #1 piston on TDC and check the timing mark on the crank pulley.Then take off the distributor cap and check that the rotor is pointed at the #1 plug wire terminal.If the crank pulley is on TDC with #1 piston at TDC and the distributor rotor is not pointed exactly at #1 wire remove the disributor and turn the rotor to line up with #1(wire).Then try it again,make sure the wires are in the correct firing order also.

Remove #1. spark-plug. As you face the fan it's the first cylinder on the right hand bank. Have someone bump the starter till you feel compression. Watch the dampener pulley THC. timing mark. Line it up with the "0" mark on the timing tab.
Pull the cap off the distributor. The rotor should point exactly at the #1. plug wire. If not pull the distributor and move it one tooth till it aligns with the #1. plug tower on the cap.
When you lift the distributor out and move one tooth it will not settle back down onto the intake manifold. because of the oil pump slot on the bottom of the distributor. There are two ways to easily fix this.
#1. Reach into the distributor hole and either advance or retard the oil pump slot so that the distributor drops all the way in.
#2. Have someone bump the starter while you hang onto the distributor housing. It'll drop back in when the oil pump and distributor slot line up.
Use an inductive timing light to properly set the initial advance with the vacuum canister hose off and plug the vacuum source.
If you still have trouble timing the motor the dampener pulley rubber collar may have slipped causing an untrue TDC mark.

Well, then reset it. Line up the timing marks on the front pulley to find TDC on Number 1 cylinder. Then pop off the distributor cap and see that the rotor is pointing toward the #1 spark plug wire(it will be close to that wire or 180 degrees out meaning it is pointing to #6,,,,,means that you have to manually rotate the engine over again and line up the mark for it to be right.(or in your case close). Then undo the base clamp to the distributor, lift up the distributor and hold the rotor and turn it one tooth worth and set back into the hole. The rotor should now be pointing to #1. My guess is that it was already past #1 and closer to #8. Firing order being 1,8,4,3,6,5,7,2 for an 8 cylinder.

There's no such thing as being a tooth off. You just turn the distributor to any orientation, so it doesn't care. You may have some wires out of order, or it's possible you just didn't set your timing correctly.

turn your distributor about a 1/4 inch to the left, it sounds like it's timed to fast! (counter clock wise and if that don't work turn it back the other way)!

as an old chevy man country boy is right on and firebird knows nothing about chevys. marks lines up twice so compression on the number one hole is essential to proper timing., right on countryboy!!

it sounds like its off a notch ,try removing it and coming one tooth advanced with it,or re-time it all together,its simpler to do this than to make several attempts to get it right,good luck.

at the dist. cap, try moving all your wires forward one spot

do you have a timing light?
