I thought you might be interested in looking at an advance copy of a new article I will posting (or something similar) The update is scheduled for the second week in July, but you get a sneak peek. This car is a freak....
How does anyone firure this to have a Cobra Jet 428?? Ford didn't start producing them until February or March of 1968. So, how could that happen in a car built in August of 1967? Show us the facts about that.
Let me clarify, the car was built with a 428 PI motor and finished at AO Smith as the first GT500 convertible. The first "owner" was "Shelby Engineering" and they are the ones that replaced the motor with a 428 Cobra Jet. They also used the car to test fuel injection, traction lok rear axle and a big block supercharger. I doubt the car had Cobra Jet in the Aug-Sep 67 time frame. The information is from SAAC and comes in the form of a factory inventory sheet of prototypes on hand. I will be massaging the information before I make the final posting in July. This car may have been a factory test car for more than a year before finally being sold to the public. I guess if factory paperwork isn't working for you, nothing will. It was not unusual for these early cars to be around for a period and then disguised and sold as "ordinary" Shelbys. The Registry is full of examples.
Re: 1968 Prototype- Clarification I should further clarify my possible misleading statement. The car is question is a really production Shelby that was used to test prototype parts by Shelby Engineering. I will be changing the article accordingly. Still pretty cool, but way more accurate.
Actually the first official Cobrajet engines were assembled in Dec 67 and were made up of components available in Aug 67. They had more parts in common with this Aug 67 car than the later April 68 released version.
