Back in the 1980s, Vince E. said he had a list of 37 1969 L-78 Novas that Yenko ordered and about 30 of them were converted to 427.

As far as I know, the production number of 427 Yenko Novas has always been about 30.
For some reason, many people use 37 as the production total of Yenko 427 Novas but it was always 30.

The list of 37 is thought to be a list for Yenko Sportscars which in some ways was separate from Yenko Chevrolet.

Over the last 30 years there have been other 1969 L-78 Novas that have been found that were sold by Yenko and are not on the 37 vin list.

So we know Yenko had more then 37 1969 L-78 Novas.

I can think of 7 1969 L-78 Novas sold by Yenko that are not on Vince's 37 list.

Cars that I heard of are; one each of a red, blue, black, brown, fathom green, and 2 rally green.
There were probably more then 7 1969 L-78 Novas sold by Yenko in addition to the 37 vin list cars.
