Think!  If the engine mount isn't absorbing/suppressing vibration and movement, what part of your car is?

the two rear mounts.

the cross member bushes.

the chassis of the car

suspension bushes

yes they are meant to for sure, but they are designed so your mum can bang over speedbumps in comfort and you simply would not believe the movement from even fairly modest power outputs.

another option if tyou can be bothered is to make up mounts with smaller rubber bushes in ( *cough* transit leafspring) so they are much firmer but still padded a little. more hassle but more proper and a not uncommon sight in the less convenient engine swaps like vtec into old mini or virtually any off road racer. the engine itself only needs to be secure and not strained (obviously the mounts do take load when the engine is working- i mean the need to fit properly not be hammered in or pulled into place with the bolts), you still often see mk2 escorts with hot pintos and sierra cossworths advertised with a 'wcxm' (world cup cross member) essentially a completely solid pair of engine mounts fabricated onto the subframe, likewise in f1 cars (okay im pushing the point a litle ;) ) the engine is a stressed member. Some tvrs and se7en replicas are solid mounted too, its fine as long as its strong and straight.

The mounts are there to make your car feel all pc and living roomy in the showroom/when whatcar test it, most well prepared track/race cars will have beefed up firmer mounts.
