first off I have no dog in this fight since I run a lowly small block but I do remember when World came out with these that every one raved on the fact that there was another option and that World had improved a number of things over all the other blocks such as oiling and 2 bolt patterns for different bell housings and such.
Now there is a problem with what seems like a few of the many blocks that was sold and now World is crap I think that some would say that's unfair.
We all have heard the many horror stories about Indy but we still buy there stuff but we have it gone over by someone we trust so they can correct any issues that there is sure to be I just wonder how this is that much different.
If i purchased a new block and saw that the studs where nor ARP I would address that right then not later and all ARP stuff has ARP right on it so there is no guessing.
Again I have no dog in this fight just my
