The balancer appears to be aftermarket. It was black at one time but now rusted. I don't believe its a Pontiac hub as it matches the originals in size and diameter. My local machine shop had never seen one either and also said to toss it. I can send you a picture if you wish to post it or see it.
TRW pistons it is and some digging on the heads. I believe they used Hard Block in the cross over's, it sure reminds me of concrete and flakes out like concrete.
The camshaft is not marked so I need to degree it and see what it is. A reproduction 068 cam should work, shouldn't it? Can we get a original cam for this engine? or how about the HCO1 cam from SD Performance, I have used it with really good results. The Summit 2801 cam is also a decent street cam.
