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??
