Several years ago I sold a stock 82 2wd truck to another board member pretty cheap.  He tinkered with it while going to wyotech, added a weber 32/36, tuned it as best he could and ran it on the dyno and got 95 hp and 130 ft lb of torque.  Sad that a stroker, which should have much more potential, go so much less.  I can't remember if he ever changed the cam, but I don't think so.
