Throw him an offer of $220 for the blower, LIM and whatever else is attached to the SC. See if he'll bite.
Other then that $350 for the whole thing is a steal. Hell it might even be worth it to buy an engine stand and a cheap storage unit to store the whole engine and take it apart to sell it all off if you play your cards right. It sounds like a lot of work, but parting out a gen 3 can yield a high return.
