Need help figuring out a noise/vibration I'm having - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My first thought is I need new mounts. After replacing my stat and belt I was letting the engine warm up. And I was giving it some gas to speed up the process. I don't have a tach so I would have to guess I was slightly over 1000rpm. And I noticed a noise vibrating in the cab. Felt like an on off on vibrating sound. Any one have any idea on what it could be.
