I have the 5.4 aluminum engine with low compression in cylinder 8 the top of the piston is pitted and they cylinder wall is scorred. It happened due to the engine running lean however the engine still runs and drives. I actually drove 40 miles to my house like that and it still pulls really good. Obviously I have parked the car. What would the motor be worth in the honest opinion of svtperformance community. I mean the entire motor including the supercharger which is stock. Any feedback is appreciated thanks.
