Here is my $.02, and its only that.

Personally, I would probably pay up to 10% more for an L78 Nova sold at Yenko Chevrolet than an L78 sold elsewhere, for instance, mine was sold at Les Stanford Chevrolet in Dearborn. I think the cool aura of having a high performance car sold by Yenko Chev is worth 10%, at least to me it is. A non-high performance car sold at Yenko, I could care less about.

However, since it has a CE block, I would deduct 10% personally, so its back to just market value for a '69 L78 Nova in need of a full restoration.

Cool car and the L78 Nova is the only musclecar that I prefer an Automatic in over a 4 speed.

With the VIN not on the list, the build time not consistent and other things that were pointed out, it sounds to me like the new owner is wearing some rosy glasses. As for the dealership asking the original owner to upgrade? I’d be more surprised if they DIDN’T try to sell him on the 427 swap. After all, that was a profit builder for the dealership’s sales and service dept. Then the service department tried again...no shock here either. Looks better to the GM rep if you sold the customer a shortblock rather than do one under warranty.
Nobody likes rare finds more than me, and as it is, it’s a very cool car, but until bulletproof docs can be found/viewed/scrutinized, I think the new owner is bold in his claims.

Saw a pair of unconverted Persol's that once belonged to Steve McQueen sell for 70K at an auction at the Pete a while back.

Sure looks like a cool car .I am confused about the 68 Yenko Camaros also non converted. So to me it’s just an l78 . Correct? Thanks

Thanks for bringing this to our attention Wes.
Personally I would've done a heck of a lot more research before displaying it to the world so soon & the way he did.
He sure is defensive on Fbook this morning,and has deleted the majority of the last two days comments that went against anything near what he wants to believe.Marlin & others were very cordial & professional,yet now their comments are gone.
It's a nice 1969 L-78 Rally Green Nova with a CE block,TH400 & 3.55 rear,but he sure refuses to see even that.
He's too close to this car as he did just buy it and can't see the forest for the trees.

VIN 11427W429738

I haven't followed anything on facebook, but to answer your question if the 68 Camaro is 9737 copo, but unconverted there's a high premium for that car.

Like previously posted, if a car is a hi-perf, and sold at Yenko there's a premium. The premium is ultimately determined by the buyer and what they are willing to pay...above and beyond.....

At least here he can't delete every comment that goes against his agenda.

All I can say is that Matthew McConaughey guy finds some cool cars.

there's a song :What a fool believes he sees

He doesn't find most of them, the owners or owners friends often time contact him though he does write some good and interesting stories. He is a good writer/videographer and makes what might otherwise be a boring read much more interesting though sometimes they are a little stretched and not completely factual (black LS6). Likely in the interest of selling magazines articles or the car itself so I can understand. I have known about some of the cars he 'found' and knew about them years before he 'found' them. I guess it could be like my recent Yenko 'find'. I thought I was the only one to see the car in many years when in fact there were several people who had laid eyes on it in recent years.

He is also a member here and has been since 2010.
