Quote: After I wrote my HEMI book, I broke a World main stud while assembling an aluminum motor. I used an iron World block in the book and had no issues so I talked to the powers to be and they said they did indeed have issues with their stud supplier. But that was over a year back, and they told me that new blocks would use ARP studs.
Than about 4 months back I had another aluminum World HEMI block delivered and it had all ARP.
one would like to think that in today's world of technology a vendor might very easily track down all the blocks using the junk studs and replace them or at least notify the buyers of pending problems. I guess their mindset is by issuing a recall could hurt future sales. A few related engine failures will cause more than that.
