I'll go with the Ford "Bluff". Don't think they wanted at all, to make that go 500 miles. Trying to remember.....was there any other racing application a cammer would have fit in? Or was it designed from the get go.....for Nascar? Agree, Ford played the SOHC card VERY well. It takes a good poker face to push for something that you dam sure don't want. In that regard, the cammer served it's purpose.
