OK, now don't think too badly of me, but....when I was re-assembling my 351W, I did not know what that round, two piece thing was for that was bolted to the front end of my old cam. So I just put it back on like it was and went on with the business of assembling the windsor. It wasn't until I installed the new fuel pump that I realized that the round, off center thing actuates the pump arm. Here is my question, how much force does the fuel pump arm place on this thing? It has been knawing away at me at night now that I am getting closer to putting the engine back in because I am afraid I did not tighten the bolt enough (I just can't remember). I don't want to have the engine in the car and the thing slip because I was too lazy to break the engine back down prior to putting it back in the car. Should I worry, would ya'll break into the engine, put some loktite on the bolt, and re-paint everything, or do you think it is probably OK.
