Damillster Erster Beitrag: 29. Oktober 2003 Letzter Beitrag: 7. November 2004 Does anyone know how much more power can be extracted from the 5000 QV (1986, fuel-injected), and still keep it NA? A 6.0L Countach would be quite a car, but I suspect that there isn't much room to increase the bore/stroke. Any guesses as to how much power is left in the motor, and how to get it?
