Quote: Was there any specific problem with the World Aluminum block that caused the engine failure ?
It's hard to say really. I don't think so though. I have a B1/MC motor out of a World block, that runs real well and it's on it's 3rd rebuild.
Nothing glaring that would cause failure if corrections are made.Rear main seal retainer fit,main cap location,uneven deck and some bolt hole depths and those pesky little bolt heads on the main cap cross bolts.Just typical stupid stuff.
