Not every 68' Yenko used that tag. The very early prototypes did not use that tag and were sold to customers as demos after there demo duties were completed...BKH

Re: Magic Mirror trim tag
 

Well, if the different trim tag was put on by Fisher Body because there was possibly a question of compliance, that would mean that 68 Yenko cars that have that trim tag are actual copo cars from GM and not motor swap cars done by Yenko Chevrolet.

May be another piece in the puzzle. https://www.yenko.net/ubbthreads/imag...ns/burnout.gif

They were COPO's because of the 9737 COPO not because of a different engine.

Does that mean the heavy duty suspension and a 140 mph speedometer could make a car non-compliant for federal standards?

No, which is exactly why i don't believe the magic mirror tag had anything to do with passing or not passing federal standards...as BKH stated, not all 68 Yenko's had the tag anyhow. I believe it was just a way the factory differentiated the Yenko cars from the rest of the SS396 cars when being built, just like the MV 396 engine code. Why would Chevrolet ship a car to a dealer to be sold to the public if it didn't meet federal standards?

That would be a major drivetrain difference. Maybe the MV engine was not emissions tested?
Me, I'm surprised at the whole 68 program......

Re: Magic Mirror trim tag
 

Major difference in what way? A COPO 68 SS396 destined to Yenko was still an L78, complete with smog, etc. I know of no driveline difference from any other 68 L78 aside from the 2 letter suffix on the pad, which I believe was done simply to keep track of the special order cars being buit for the Yenko COPO order.

Re: Magic Mirror trim tag
 

Did Brian note if the 68's Yenko's without the Magic mirror tags had the 9737 package ?

Re: Magic Mirror trim tag
 

It's known that the MV engine had different components. The carb for sure.
COPO orders were done all the time without special engine codes...

Re: Magic Mirror trim tag
 

The gibb nova 396 suffix was E3 but the engine had nothing different than any other 396. I feel the E3 meant expermental 3 speed for the auto trans. Maybe GM used this to track them. Maybe they did the same with the MV suffix for the Camaros??
