Timing Chain Tolerance

[The Dart GT]

I'm rebuilding my 225 and when I pulled the timing chain cover I noticed just over a half inch of play in the chain (slop). Is that acceptable? Thanks

By the book, 1/2" is the maximum tolerance.

I also noticed that the teeth are fairly flattened out. Shouldn't they have more of a point on them?

If you are that far in and don’t replace it?!?
It’s a wear item.
It’s Rustyratrod.

That's what I was thinking. It's an easy replacement so I'm just going to buy a new one with new sprockets Thanks for the opinion.

I wouldn't run it, it's just going to get worse.
If you're "rebuilding" the engine, I can't conceive of not replacing the timing chain.

Looks like it already had an upgrade replacement timing set on it at one time. Step it up a notch more and get a true roller for it. And while your in there. A Mother Thumper Cam and a header.

I bought a 225 not long ago with a hole in the timing chain cover because the sloppy chain wore through it.

I lucked into a MP timing set from back in the day for mine (double roller)
