A little known fact about the #40 turbine car was that it was SUPPOSED to be ready for and entered in the 1966 Indianapolis 500. It was a complete secret and had only been discussed with USAC in vague terms for its legality to the rules. Unfortunately, the frame was warped when it was improperly heat treated and the Granatelli's had to enter the Novi car in its's place. 1966 marked the last year of the Novi's at the Indianapolis 500. By the time the 1967 event came up, the car was no longer a secret although many of the details were still unknown.
