While we're waiting on the metallugical report from Challenger340, does anyone know what specs these studs should meet? I wonder why the world rep. would say that their studs meet mopar specs. It's not a mopar-built block, and not an OEM application. If the ones tested meet ARP specs, or fall way below, the answer is clear. But what are the real minimum specs these studs need to be??

It's my understanding that these blocks were built to replace the MP blocks. My alum. block says MOPAR on it.(see pic) So the World Products tech was saying that MOPAR specs were complied with for the main studs.I would be surprised if these studs will meet OEM requirements if so many are stretching or breaking. It would be interesting to know what those specs are.
