Evaluate Timing chain sets

You need to go back and re-read the article, that info is not from hughes that is the opinion of Chris Holley for mopar connection. This pic is directly from hughes website and clearly shows a double roller. Why don't you actually call hughes rather than try to find web articles to support your opinion.

Funny they even mention "race engines" in the listing.
The info on using the hughes tensioner is correct in the article I posted. Looking at the photo of the slack in that chain you posted. I would say you would need a tensioner with that. I've seen used chains with less slack. Wonder what that thing would look like after a couple miles?

With a chain that bad you would have to allow for 500 mile slack on install when degreeing it. I would be ashamed to post a picture of a new chain with that much slack. Whats with the punched pins on the Chain? Who makes that chain?
