i don't know.. dyno engine? was it beat all to hell on that dyno? no specs? any proof it runs and doesn't have a spun bearing or anything? looks like a core to me.. 2k is too much for a core in my opinion...
JMHO, but if it was me I would consider that a "core" and I wouldn't run it without a teardown and inspection. You have no idea what someone else did, or didn't do.
