Default How much horsepower on motor mounts?

Got a 68 Camaro backhalf car with a BBC around 675 h.p. on Moroso solid motor mounts and a stock trans mount. Thinking about upping my game this winter, possibly a 540 or triple nickle around 850 horse. When do you need to use motor plates and mid plates? Is there a rule of thumb?
