Message: [QUOTE="Morgan@Midwest Diesel & Auto, post: 1178736, member: 8143"] I disagree. When have you ever replaced a worn crank gear? Oh yeah, never. They don't wear out or need serviced so who cares if they are welded permanent. You can key it or weld it. Same difference. I've done it on several platforms. Also, please, can anyone prove to me or anyone else here the actual quantitative strength added by main studs? I have yet to see any of the factory 6 bolt mains stretch. And contrary to popular belief, main studs do NOT make an engine block stronger. The 6.7 block is not as strong as a 6.4 that's all there is to it. But no one in this forum can actually prove that the cranks flex or that the main stretched. Because they most likely didn't. Some of the early cranks have broke but that was mostly due to casting flaws. I've pushed 12mm 2 bolt main block engines to 1000hp and 8000 rpms... I think some people are overlooking the obvious or trying to push blame on things to cover their own behind. This is about as pointless as main studs in a 6.0 or 6.4.... But hey, what do I know.
