Default Re: Knocking

I had the same problem with my engine . Timed it by the ford service bulletins to get in the ball park and then I would experiment with the dis. cam setting . I would retart it a little ,test drive ,retart some more test drive ,until I found where it ran the best with out rattling ( knocking ) when the spark lever was all the way down. Run high octane gas and GAV at half open . Solve the problem .
