There were numerous dealerships that did 427 conversions in Camaros and Chevelles in 1967. None needed permission to do it.

The Yenko VINs are known, but unfortunately most of the others are not. So docs are needed for proof.

So if this VIN is not a know yenko VIN and the documentation was truly burned in a fire this is nothing more than a 67 camaro with a 427?

Basically yes . You could send to NCRS to see what selling dealer was and perhaps dealer had known ties to Dick Harrell know installs.

Nickey Chevrolet in Chicago also did Camaro 427 conversions. Dealership is long gone, no paper work known to exist.

1967 yenko- harrells are known to have a fleet code on the cowl tag. That said i am not sure they all have the code but my harrell has it

Yes. Evaluate the car for what you can see and verify, that will tell you the value. If the car is a Yenko, I'd imagine the seller or previous buyers would have verified it by now - lots of people think they are the first to 'discover' a car, only to find out that it's been well known in small circles. So, be careful.

there was a deal with Yenko and Dana chev in late 1966
where Dana was to sell the Yenko Stinger Corvair and Yenko was to sell the Dana 427 Camaro
There were ads run in magazines and newspapers showing this but it is not known if any Dana 427 Camaros were sold by Yenko

A new deal was made with Dick Harrell in 1967 for building, selling, and race car sponsorship for 1967 Yenko 427 Super Camaros

Three special order unconverted Yenko COPO Corvairs were sent to Dana

this article has some info on them
