Whether it can be saved or not is dependent on the damage. If a rod seized on the crank, you can replace the rod and turn the crank for undersize bearings down to 0.030" undersize. If the crank is hurt beyond that, then a crank replacement is in order.
If the crank screwed up one or more main bearings and the saddle of the block, it can usually be saved anyway by align boring the block.
As far as buying a crate motor, I won't do it. I want to measure and choose everything myself. I simply do not trust anyone. If there is any opportunity at all to cheat, somebody out there will do it. That's Murphy's Conclusion, filed right before Murphy's Law.
