When you run a compression test, you are really looking for a cylinder that is way out of line with the others. 40, or 50 lbs lower than the rest, would indicate trouble. As for a number, well there is a lot that contributes to the actual answer. On my race engines, I come in as high as 180, to 200lbs. A motor with 80,000 miles, and 8:1 compression, would be lucky to put up 100lbs.
