Why else would the foremost installer of big inch engines in Superformance use rubber mounts? Think about. They charge mega bucks to make turn key Superformance cars for big rollers with large cash rolls and little mechanical skills. If they thought that they were gonna get a bunch of warranty claims back due to to bad motor mounts that caused body damage due to side pipe movement would they use rubber motor mounts? No way.



Sounds like you fall into this category. An engine with a fair amount of torque, which a lot have on this forum, will rip a set of rubber mounts apart in no time. Tranny mounts included. Higher amounts will also fatigue poly mounts in couple of years. If you're running high horse and torque, it's best to check your mounts a couple times a year, and replace after a few years.
