What was the horsepower of these v8 motors ? Are the MOTOR parts easy to find ? What would be the value of a good head off of one of these motors?

This was aaa beautiful car,recently brought to the yard,any parts of value ,rare?

268 hp in 92, then 275. Parts are not hard to find for the car. Not sure what a good head would be worth - not many engines get rebuilt. Fan clutches are very expensive on the car. Engine actuator, mass air flow sensor, EZL (ignition control module), and engine wiring harness would be worth saving. Wiring harness would have to be a replacement to be worth anything.
