V8SHO.com, as of today, has listed 874 cam failed cars. This is probably only the tip of the iceberg, as probably a low percentage of failures are actually reported to the site. Ford produced a little over 20,000 V8 SHOs. As you can see, this is a very high percentage. I would not be considering, if I were you, whether or not my cams might fail, but WHEN they are going to fail. NESHO (Kirk Doucette) is your best bet for welding. He has welded over 1000 cars and is the best in the business. They take their show on the road and visit various states and provide the cam welding, intake cleaning, and 100k service in one package.
