From what you've seen when OEM 440 forged cranks develop cracks, do they tend to show up in the same general area, e.g. are they more likely to occur in the main journals than the rod journals?

Also, do the upgrades (band-aids?) that can been done w/ an OEM block, for example using a girdle, cross-bolted main caps or aluminum caps, seem to have any influence on where the crank cracks develop?

Thanks!
