Timing Chains

I've used Cloyes many times in GM engines and never had any problems. I put a gear drive in a friends T bucket with a SBC and it was one of the noisey ones which he wanted. It was noisey alright, so much so that I could feel the vibrations from it in the steering wheel. My thoughts were, if it makes that much of a racket, its probably transmitting vibrations into the valvetrain. I hated it, he was happy because of the noise.
