Who here is running a fiber gear? I was told to use one as they run quieter.

Hi Z28, The fiber gear was used in passenger cars and the metal one in trucks.

Fiber is quieter, metal is more durable.

They are interchangeable so it is a matter of preference.
If I was going to use a more aggressive cam or stronger valve springs I would tend to the metal one.

Cheers Kiwi

Having blown a fibre gear I’d suggest getting an aluminium gear.

The fiber gear will eventually fail even with the mildest stock cam. I always install an aluminum gear in any engine I have apart for any reason. The noise difference is barely noticeable.


Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

Okay thanks. I'll pull the old one off the stock cam and put it on
