For 95% of us a GOOD Quality timing chain is as good as either of the high end solutions.

If your rebuilding your race car eng a lot. the gear drive would me money ahead in the long run.

If 1,2 or 3 HP is a big deal to you, then a belt drive will work better.

If i lived in one of these categories and i do, that is how i would choose my set up............Yeah i'm the 95% guy.

It’s only good if you love to run extra piston to valve clearance, or you love watching the timing move all over hell.

In 30 years my gear drive will still be as accurate then as it was when it came out of the box. No timing chain will ever last like that. Ever. No belt system either. It’s not always about horsepower. It’s also about durability, accuracy and value.

A timing chain is like stepping over donuts to pick up a dog turd and then saying you got a sweet deal.

As for valve train issues I’ve never seen them ever. And I don’t use gear drives just on my stuff. Plans are in the works for a SBC this fall to be upgraded and updated and it’s getting a gear drive. Because accuracy, durability and value matter.

99% of ALL valve train issues are either geometry or spring load or both issues.
