Alan,
Here you go ... the Ford specs are available, just have to snoop around.. Ford has deleted this link, but I have the downloaded pages in pdf form , seems cant upload a pdf file here on this site..
https://media.ford.com/images/10031/...g_GT_Specs.pdf PM me if you want a copy
Also, find a friendly Ford tech to "acquire" one of these DVD's, just remember to set your computer yr/mo date to the DVD yr/mo date.
All the info you need for stock... for pure stock you have to go to an outside source for the cam overlap/duration specs.
Hope this helps...
