So I have a bit of an issue. A few years back I purchased a 383 shortblock from a builder. The crank used was a Scat 9000 series which utilizes a key way so I purchased a Pioneer Automotive hub to match it. I noticed when installing it that there appeared to be a bit of clearance between the crank and hub but that was mostly taken out once the key was used.

Fast forward to a week ago my hub and balancer flew off while driving on the street. I went ahead and mic'd out the crank snout which turns out to be right at 1.208 about 4 hundreds off of the stock 1.25. So I called scat which basically said there was no recourse except for me to tear the motor out and return the faulty crank- this of course is something I'm hoping to avoid.

Does anyone know whether there is a company that offer custom diameter hubs or perhaps a sleeve of some kind? Any help is appreciated.
