Did you check your motor mounts?
You'll get more answers if you post this in the right section. Go to the 1979-1995 GT section or the specialty cars section for Saleens, etc.

Re: 89 saleen

Motor mounts or harmonic balancer would be the first things to look at...

Re: 89 saleen

Then I would seriously look at the balancer... is it original? If replaced, are you
sure it is the correct one for the motor?

No prob, just wanted you to have the most exposure for answers.
Have you watched it at 4500? Maybe a pulley is off balance and causing serious vibration at high rpm.
