I wouldn't worry about if it would work. But why bother? By the time you get them made/machined, you could just buy the right crank and be done with it.

I appreciate all the responses about this. Fact is, I wanted to know if it’s been done, simple question. Will I do it, probably not at this point, just wanted some input on the subject.

If they were available I'd probably buy a set. I have access to a billet center weighted 400 mained 4.300 crank.

Why stop at that size, go smaller, after all, smaller journals make more HP. It's not some voodoo thing.

Size matters, especially when it comes to twisting and reversing metal repeatedly work

You mean like Johnsons rubber cranks Line was complaining about?
Speek get of cranks, go to the general forums and look at the Cummins engine dyno explosion. Had a good one in it, for awhile!
