Not sure if I have a picture but I'm sure it has been posted before - maybe in a magazine or online article. But if you look at the front face of your balancer, you should see one of the 12 symmetric holes is circled by orange paint. You may have to look closely. That hole should be lined up with the crankshaft key that aligns with the crank sprocket. This indicates #1 piston at TDC. If I come across a picture will let you know.

There is also a hole in the rear of the crank that indicates #1 TDC. This is the hole that indexes the flywheel to the crank and is at the same degree of rotation as the front keyway. Hope this helps.

Thanks I will call ATI, appreciate the feedback!

I would call the shop who sold you the ATI pulley; indexing would be installing the stock pulley at the same point it was removed, or with an ATI, set it up with the degree marks with cyl 1 in the correct spot
