Predator crankshaft 301cc?

Looking for a crankshaft for a Predator 301cc engine. Anybody have one? Even a damaged short block may do if the price is right.
Vpowerequipment sells the stuff they refurbish from Harbor Freight. They should have some motors that are too cosmetically challenged and may be able to make you a deal.
I will look. I bought it thinking a GX390 or GX340 crank could be swapped in but I think it is more of a medium block than a Big Block. Side by side with the 420 predator it's definitely different.
