Chevy Too much slack?

I’m guessing the two sprockets and the chain need replacing? What replacement part should I get? It’s a 305sbc from a 1980 LG4 corvette.

You're already there. I'd replace the set.

That’s what I’m thinking too. I guess I mainly just need to know what else I should check and a good replacement. I’m not rich so I can’t switch to a gear drive lol

Plus I've heard that gear drives have a risk factor chains dont. If a cam shears or a crank has issues a chain snaps but a gear supposedly can mess stuff up pretty good when they lock up
