Still don't know for certain. But based on the research and info we have, we know that the 427 Conversions were ready to roll prior to Dec '66. Nickey was advertising 3 "ready to drive away" 427 Conversions in at least one magazine dated November 1966.

The objective was to get 50 completed and sold as soon as possible. If you look at the initial advertised price of the conversion Camaros you will see that they were not holding out for big profits.

The factory did not hesitate to roll out the SS 350 Camaro, as it was more profitable than a std base Camaro and there was a pent up demand for GMs new "Pony" car.
