Would you reuse it?

Nylon coated teeth on timing gears have a notorious and well-deserved reputation. That is, the OP should pitch it in the trash can.

By the way, all nylons are hygroscopic which means they absorb water. What happens when nylon absorbs water? Here are a couple:

1) dimensional changes (that can't be good!)

2) strength and stiffness are reduced (that can't be good!)

Back in the day, I knew people with big block Pontiacs and Chevys that had failures between 50k to 60k miles. I managed to get around 110k miles out of my 318 ('71 Satellite) before I changed it to a double roller timing chain. The nylon coated teeth on the original cam sprocket were worn virtually to a knife edge. Lots of slop in the chain and the timing mark would wander around quite a bit at idle. In the 1980's I bought a nice non-running '72 Fury III with less than 120k miles on its original 360. The timing chain had jumped and the owner, in a fit of rage, sold me the car for around $110. Easy fix and the local Dodge dealer gave me a 20% discount on the double roller gear/chain setup and other parts.
