Here's what I came up with about a year ago:
RAV page I never did any follow ups because of a lack of help from Pontiac engineers. I found one engineer; Jonny Williams, that came in on the tail of the program but he did not offer any data or facts. Either time has erased all such info, or they still conceal it.
I saw John Sawruk at the POCI earlier this year, he had a few "secret" documents he shared on the over head. Non concerning RAV, but it's safe to say such secret documents did exist at one time concerning RAV. Just a shame we will probably never see them.
