I just picked up a complete 292 fan to flywheel, air cleaner to oil pan plus alternator, starter, motor mounts for $100. Has 100k miles on it, clean oil in the oil pan, stored in someone garage since removed from vehicle.
You should be able to try to turn it over to see if it is locked up or not. $200 seems high to me if it is potentially just a core. If any water in the oil, price drops in half.
