hmm.... all motors shake a bit. Could have a premature shot motor mount... buy a new GM one or RKsport carries aftermarket ones to reduce play in the motor... but you will feel more vibrations becuase all the energy is transfer through the frame... I have bad vibrations in my car while accelerating but i'm almost sure its due to having blown struts from the shitty lowering springs i put on OEM struts... and it only occurs at certain torque levels... but thats not your problem... check those motor mounts first.
