If this engine is an original RUF SCR and it was mine I would restore it to 100% originality.
It had 215 hp at the crank when new so to make 193 at the wheels. That’s approx 230hp and 327Nm torque at the crank. This is just mind-boggling numbers, even with SSI’s
You have a real great and healthy engine [emoji106][emoji2]
