so two cars claim to be the first Yenko 427 Camaro.

One build date seems too early and the other too late.
I have not seen any documentation that shows the first Yenko 427 Camaro.

There is a third car that may be the first built.

The early ads show what I think is a Butternut Yellow black top SS RS. There is a Dec. 1966 vin number but not sure if it is the BY SS RS black top car.

Yenko was sending out 427 Camaro info to his dealer network in late 1966.
This info contained a photo of the black top SS RS with side pipes, 427 emblems, and mag style wheel covers.

Yenko may not have had a 427 car built by Dec. 66 but how long can he promote the car before someone would want to see it and test drive it?

I don't think Yenko could put off showing a real 427 car until March of 67.

attached the photo used on many early ads

attached a letter from Span Inc. signed by James Spencer where he replies to a dealer with info on the Yenko 427 Camaro.
This letter is dated Dec. 29, 1966.
