2006 dodge 3.3 timing chain slop.

Drive it.
Those 3.3 pushrod engines are pretty reliable.
Yep, steel gear and no tensioner. Cam in block, relatively short chain.
Remember those are not OHC.
I've seen well over 300K on those with no issues on timing chains.
I bet if you put a new chain on it, you'd probably see close to the same slack.
