If tuned correctly yes.
As far as power, your front diff. probably wont hold up too long if it isnt already replaced with an LSD. Otherwise, as long as you dont try to produce more power than your engine is willing to provide, you should be OK. If your tranny is already grinding due to wear, dont expect the syncros to hold out much longer.
This is all assuming your engine is well taken care of. If its been abused in the past, or isnt running well now, adding that much power will only make it deteriorate faster.
Mileage doesnt matter. I would take a high mileage very well maintained car anyday over a low mileage abused one.
