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

I dunno, my old 340 ran better and better at top end as the chain wore. 'course, it got to the point that advancing the timing was the only way it would start. so, every nine months, it got a new chain.
Well yeah, it kept on retarding the timing. As you retard timing, it increases top end power. To a point. lol
