    What’s everyone’s take on fitting gear driven cams in a Twin Cam motor? What are the advantages?

    If you’re installing hi-lift, long duration cams and hi-pressure valve springs, you definitely want gear driven cams. For stock or mild street cams I’d stick with the chain.

    Gear driven cams can whine a bit, but are way stronger

    Because of manufacturing tolerances, some engines are noisier than others. Same goes for gear driven cams. Personally, I don’t mind the whine

    I agree with @ted12. Twin cam owners were spooked into thinking they needed gears becasue of the problems with early twin cam chain tensioners.

    Thinking about a ’02 FXDL a neighbor has, almost done resto project. Hasn’t touched the motor (duh!). What’s the gaff on swapping to hydraulic tensioners or gear drive? Anyone with real experience
