Please consider posting on the following on the website.
Yesterday I called the Ford customer service contact number. I initiated a dialogue with a service rep and he recorded my concerns about the SHO camshaft failures. He said that there was no indication of a campaign to address the problem. I suggest all V8SHO owners/members do the same to establish an owner's record on Ford's database for the future. It may make a difference if the worst were to occur and you need to negotiate the repair costs, and it will also bring more visibility to the problem. The number is 1-800-392-FORD.
