Ive got same clutch in my 88 GT, it smelled like clutch for about the first 1500 miles, and i tried to break it in as easy as i could for the first about 600 miles. The smell went away on my car. I got it the most in reverse i had a steep driveway. I think you may need a stronger clutch, try a stage 2. Your car has the max hp/torque rating on the clutch almost stock. 2000 miles you shoulkd not smell clutch anymore??
On the spec website it says 420 torque capacity i have no where near that N/A so i don't know but the smell has gone away so far after a few hard runs today so i maybe it will last another 3 months till i deploy
My stage 1 installed last September (maybe 5k ago) still smells on a steep hill start or a if I rode the cluth a little bit. The clutch grabs hard as my best dyno run ever was using the Spec clutch. I probably would not put another spec clutch in next time, but I was unhappy with the lift of my stock clutch as well.
