Off set crank grinding

You are all forgetting the most important thing. Re-harden the journals. It will cost you more to grind the crank and re-harden it then it would to just get a crank from Ohio crankshaft. Did you ever see a crank after you go through the hardening. A crank should look Chrome when polished you won't get that out of a unhardened shaft and it will hammer out and egg very fast with some serious boost or compression. A good heat treated bearing would be harder then the crank.

The most important thing on making serious HP is that it has to live. Or what good is it? Big muscles are useless if the heart can't take the extra load. Just a thought.

Also the only time you would want a GM sized rod is when you need a small pin because the block is decked to far for your stroke. It keep the pin under the compression rings. I tried it. Don't do it they are grenades with the pin pulled.
