That's sounds like pretty good compression to me, almost a little high really, but I don't know what the speck is on your car. I really wouldn't think with that high of compression you are burning oil that bad. Like I said dark black smoke is raw fuel you might want to look for a vacuum leak, maybe the m.a.p. sensor is not correctly hooked up, and it's signaling a rich command, and it's just dumping fuel into the cylinders. From my experience everytime I've seen a car run funny after i've worked on it and it's blowing black smoke out the tail pipe it's always due to a vacuum leak or the m.a.p. sensor came unplugged or lost it's vacuum source.
