Ford has recommended most of their engines switch to a 5W-20 oil. The V8 3.4 SHO is NOT one of them. Stick to your 5W-30 oil. And, of course, get the cams welded. Otherwise you are looking at engine failure.
BTW, buying a short block directly through Ford is still about $12K, so do the preventive work. Through ebay is about $400.
Individual components for this engine are pretty high and will remain so. The weakest component of this car is still the tranny.
