You will see a dimple on each gear. Install the gears with the chain on withe the dimples facing each other. The top dimple per say at 6 o'clock and the bottom one at 12 o'clock

To start with, You need to turn your engine over BY HAND, DO NOT use the starter.The reason for this is with the #1 cylinder plug out, you will zip right by Compression stroke on just momentum from from the crankshaft alone once the starter gets it moving.
Take out the #1 spark plug from the cylinder, put a paint ball, cork or even your finger OVER the hole, NOT IN the hole.Putting your finger IN the hole can force fuel under your fingernail to the nail bed, and you can loose your finger from that practice.
As you are standing in front of the engine and looking down at it, you want to turn the crankshaft CLOCKWISE.
Finger OVER the hole, turn the engine over BY HAND until you feel compression start to build in the cylinder... This is the COMPRESSION STROKE. The piston comes 'UP' on Exhaust stroke, and a common mistake is to find TDC or Top Dead Center of 'Exhaust' stroke instead of COMPRESSION STROKE...SO,Find Compression Stroke,
THEN...
Take your finger off the hole, and use a WOODEN DOWEL ROD (chop stick, kabob skewer, ect.) to feel for the top of the piston as it comes up.DO NOT USE METAL!
Once you have turned the engine so you believe the piston is at the top of it's travel,That would be TDC or Top Dead Center.
Then take a look at your distributor. Find the #1 spark plug terminal, and make a mark on the distributor HOUSING below the distributor cap #1 terminal.
Flip the distributor cap and see if the rotor is pointing at the mark you made for the #1 terminal (Within a few degrees)
If it's (Clockwise) past the #1 terminal mark, you set the distributor on the wrong tooth when you installed it.
If it's pointing directly away from the mark you made on the distributor housing, you have the distributor in 180 degrees out, or TDC of Exhaust Stroke.
Remember, there is a spiral cut gear on the end of the distributor, so as it engauges, it will move 'Forward' following the gear teeth... SO, Once you find TDC of Compression, you need to point the rotor at the #1 mark, then back the rotor up (Counter-Clockwise) about one cap space, or about 1/8 turn, then install so when the gear engages, it will pull the rotor into the correct position.
The Distributor might not seat on the timing cover fully... This is common, and it's just the oil pump engagement not lining up correctly. Grab your crankshaft wrench, and turn the crankshaft TWO (2) Full Revolutions CLOCKWISE while applying slight down pressure to the distributor...
You will feel the distributor drop into place, but continue with the crank until you have completed TWO full revolutions...
Anyway, when you have VERIFIED... VERIFY you are on COMPRESSION STROKE, VERIFY you have TDC of the #1 Piston, VERIFY the rotor location (pointing at #1 terminal), VERIFY the balancer...
Once you have TDC of COMPRESSON STROKE, and you have taken a look at the distributor rotor, Have a look at the harmonic balancer mark.It should be at, or very near, the 0° (Zero Degree) mark on the timing cover scale.
IF it's not, you have not located TDC correctly, OR, The balancer is screwed up, which is pretty common. (and it's REAL HARD to screw up TDC location by removing the #1 plug and manually verifying the piston is at TDC)
This should give you some idea of what orientation your distributor should have in the engine
Please give more details related to the problem.Please mention what part needs to be checked.Also mention about the problem in bit detail so it can be helped in much better way. Thanks.keep updated.with more details.

Can you tell me what an ARE is ?
You will see a dimple on each gear. Install the gears with the chain on withe the dimples facing each other. The top dimple per say at 6 o'clock and the bottom one at 12 o'clock
the dimples will be on one tooth on each gear toward the top of the teeth

And this will show you how the cylinders on the AMC V-8 engines are
numbered...
How may i help you further ?
