The 427 NASCAR cammer that they ran at Le Mans scared all the drivers they had except for Mario and Lloyd Ruby. Ford had to bring A.J Foyt and Dan Gurney for testing.
A.J.,Mario and
Dan Gurney,,,
Test Pilots All!
Tom Sneva would do Well
In the Company.
Mario said the original 289 motor didnt even go fast enough to charge the battery LOL
What made the cammer great were the massive heads and it was a great engine for unlimited type racing in all motorsports from drag racing, drag boats, NASCAR etc. It was a great response to the Chrysler 426 Hemi. But due their size, scarcity and limited specialty parts as a result they had a relatively short run as pony cars ruled the era and were unable to make them fit.
