Meet the Mean Ones!

[YENKO DEUCE REGISTRY]

Good questions, tough answers! I'll take a shot at it.

The first order of '69 COPO Camaros was the 50 X66 cars, and the earliest build date that I know of is 01B. I know that the second order of 100 cars was placed November 11, 1968 and they were built in March of '69. So, logic says that the first order of 50 was placed prior to 11/68, but... I think Ed C has the exact date.

Regardless, the earliest '69 Yenko Nova has a build date of 01A! Two of them to be exact. So, it appears that Yenko had the Nova in mind along with the Camaro. I'm not sure about the Chevelles.

I guess the sketches must have been done post December 69, or Don wouldn't have even known what a cold air hood would look like. I'd bet it was before he saw a Z/28 equipped with one too, or he'd have used the rearward placement for the engine numerals like GM installed the Z/28's 302 badges.

Maybe the Camaro in the sketch IS the gold demo car, have any other 69 Yenko Camaros been documented to have received the demo car's emblem placements?

Ed Hedrick's early X66 car got the crests below the Camaro script, and the 427's on the hood, but the same tail pan treatment as the demo car with the '68 style 427 emblem placed on top of the blue bowtie. But it too has inexplicably shown up in pics with the "standard" staggered crest and 427 tail panel emblem placement. I know at least one 69 Yenko Camaro is documented to have received no Yenko fender crests at all.

I wonder at what point did Yenko develop the "standard" emblem placement we see on most Yenkos today? Was he ultimately responsible for switching the tail pan setup on Hedrick's Yenko sponsored racecar?

It seems every answer just leads me to asking more questions.

I personally always wondered why the early cars had 140 speedometers, yet there were no in-dash tachs until the May built cars...I always figured it was probably a factor of Yenko being "cheap" and assuming he could install SW units cheaper than GM would sell him a factory in-dash tach, but doesn't explain why there was ever such an item as a speedometer that read to 140mph... Even more odd is the fact that the 68 L78 COPOs had these 140 mph units too.

My guess would be Don's road race mentality. After all, COPO 9737 is more of a road race type package then a drag race package.

hard to say why Don did some of the things he did but also some things may have been directed by Chevy engineering. As Tom said Yenko was always thinking SCCA road racing and the Yenko Camaros were sort of like 427cuin Z/28s. Maybe Chevy engineering designed the car for high speed use like the COPO police cars which also had 140 speedos. Maybe Chevy wanted it in the COPO Camaro but then why didn't the Chevelle get the 140 speedo?
I am still trying to figure out why Don ordered rear antenna on the Yenko Chevelles.

[/ QUOTE ] Maybe just because it looked cool and was what Don was used to having on his Corvettes?

Wasn't the rear, telescoping antenna standard with the AM radio, while the front, fixed mast antenna was for the AM/FM...
