Thanks for the pics.....I had another engine rebuilt on another car and noticed that the distributor was wearing the gears from side to side and not in the middle. I put another distributor in for a little while and found that the distributor was wearing the same way. A friend of mine put this block together, but he never builds six cylinders he is more of a big block guy and he had no clue about the cam spacer. Another friend brought the spacer to my attention, so we are going to pull it apart and make sure there is one there, and if not we will need to put one on. I found one local too, but I was still wondering what type of damage could be done if you drove an engine like this without one? and could I simly fix the problem by putting one on?
