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!
nice , i always go forged be it pistons or crank , people say i'm crazy not needed cast crank and hyperdodo pistons are good enough , well maybe , so far have yet to have piston or crank problems in over 20 years of beating the crap out of my cars , with todays gas imakes sense to go forged pistons , had a few times where the gas was crap and pinged like crazy maybe the cast hyper pistons would be fine , i'd rather not find out . i like to build once properly .
good luck with your car hope it is al you expect
