Let's just say a long time. Timing belts didn't come along until the 1970's.

All of my early 1970s Porsche 911s had timing chains.

Initially it was timing gears. Then timing chains became the status quo. Then timing belts came into fashion. And now it seems timing chains have had a resurgence.
Yep,
It's worth mentioning that sadly modern timing chains usually do not last for the lifetime of the engine - I really wish they'd use easy to replace timing belts.
