Replacing a crank shaft questions

Update:

The SCAT 48005BI is actually the forged version of their 340 offerings in a 3.58 stroke. That's the direction I went.
Also, that balanced kit comes with pistons for a 4.070" bore, so if yours has been bored previously, you will want to make arrangements for bigger pistons. No big deal but in my case the financials actually favored re- sleeving the block.
I'm still $3500 ahead of a modestly priced crate motor (so far). If anyone else is keeping score!
