One issue usually associated with the used Cup engines is that the factory engine mount bosses on the driver's side have been milled off for dry-sump pump clearance which makes it a necessity to use motor plates. A friend has bought probably a dozen used SB2's from RCR and they were all this way.
Another issue for street use is that often the stock oil filter provision is gone too since they run dry sump with a remote filter.
