Author's Note: Will new motor mounts increase engine response?
People have used hockey pucks as motor mounts. It's true. I've seen it. It's not really recommended, but about 10 years or so ago, when I was regularly hanging out with a group of guys who performed engine swaps, it was considered an inexpensive way to get a high-performance mount. Metal brackets were not considered necessary.
Hockey pucks are made of hard rubber that's very similar to an engine mount. I'm not recommending it, and HowStuffWorks.com certainly is not recommending it. But it was the first time I'd considered the concept of "performance" engine mounts. And I guess the highest-end polyurethane mounts available at the time just weren't good enough. Or perhaps they were too expensive. In fact, there were plenty of things in our world that were too expensive at that time ... like any car less than 15 years old. The boys bought hockey pucks in bulk. I didn't. My car rattled enough as it was.
