Well now, that opens up lots of possibilities. Did you convert the 5.9 to an LA timing cover and V belt drive? Or leave the Magnum timing cover and serpentine drive on it? If you converted to the LA cover, the answer to your original question will depend entirely on what year timing cover you used.
Damn, I had the engine built by someone out of business now. It does have v belts. Looking at my spec sheet it says 360 magnum core, does not say anything about timing chain cover. What would identify it as a la cover?
