What's your opinion on the slack in this 318 timing chain?

no I don't have a degree wheel looks like I'll have to buy one :thumbsup: hoping i could advance it 4* and let it eat
You might can......but without a wheel, you'll never know. If you get a degree kit and it's spot on dot to dot, then great. The chances of that are very small. That's why I always recommend degreeing.
