B&S Raptor Engine Pricing?

#1
What seems to be the going rate these days for Briggs & Stratton Raptor engine that is still new in the box?

This engine was sold new, unassembled & it is still in the same condition.

I don't know very much about the Raptors. What is so special about them & how do they compare to a B&S 5HP I/C engine?

Do the Raptors have an aluminum bore or are they sleeved?

What's the deal on the amount of crankshaft bearings & what is the most desirable configuration?

What else should I know & what should I be looking for?

Thank you
