I have to assume that no matter which company finishes them if they are overseas forgings they are very similar in overall strength. I'm sure some have been broken and I have spoken to a few in the bowtie camp that have broken an overseas forging, but that's where the story ends. No hows or why they failed. Mr. Kinsler's information is priceless as we all know the level of power he makes.

I agree with all the above. Sometime research the 500557 block lol. We've used a handful of SGI cranks and never had issues with there cranks. A couple had oversized main journals but we skimmed them down to STD spec. For a while they were the only option for the 3.25 main 4.5 stroke crank.... they might still be??
