Has anybody used or installed the camshaft snout extension kit that Hughes engines sells? I am trying to put one on my 1991 360 motor and something just doesn't look right. Don't know if you need to remove the key from the cam or not....

I looked at it and put it together tonite the way its says to and it seems like there is nothing in the way of a key-way to hold the eccentric in place. What am I doing wrong here?

I've never used one but can you post a pic?

I have one in my Magnum based stroker. I don't remember any issues installing per Hughes instructions. It has worked for a few years now. As stated previously can you post a pic??
