I run an old Ed Pink 8-71 race blower on my GTO and a couple nights ago at cruise night I noticed the hub had slid out and my belt was dancing around. The hub is a BDS unit for pontiacs and I was using the factory crank bolt to hold it. It looks like it became loose and the hub was working back and forth on the key causing it to wallow out the keyway in the crank and then the bolt broke and it split the crank hub up through the keyway.
Since I am now having to change out a perfectly good crank is there a better hub or system than what I had? If this had been an exepensive forged or billet I would be really ticked but right now I am “only” looking at about $1200 to fix
