ok just curious & making a suggestion the cam would probably be ok, its not like its a huge cam with high spring pressures that would scuff it up in such a short time. did you mean the MTP-1? dont see a stp listed for pontiac. & rock auto shows its out of stock... also consider new lifters if youre replacing the cam, they are just as important to break in to the cam.
looking at the specs, that is a very small cam, you could go quite a bit bigger in duration & lift & still have plenty of vac for brakes or a/c. im not sure what the engine specs are but for a 400 you could go a lot bigger to get more power & bigger rpm range & still have plenty of vac. im not a cam expert to give specific suggestions but maybe some others can suggest another cam or post a new question asking for recommendations based on the engine?
