Magic Mirror trim tag

[Kurt S]

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...

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??

Sounds reasonable to me Kim... Whats different about the carb or any other components on an MV 396?

[Kurt S]

But the Nova engine was very different assembly than the standard L78. It had a flexplate attached.
I like that suffix theory.

I don't have the carb info in front of me, but I know it was different. Fran pulled the bill of materials for the motors.

It supposedly had the R4054 68 Corvette 427/425hp carb instead of the normal 396/375hp carb. But, a lot of special carb motors (including ZL-1's) didn't get the carbs listed on the spec sheets due to limited avaliability.

Another good point John. Back to the original question, Kurt, what proof/documentation do you have that shows the use of the magic mirror tag on 68 Yenko cars had anything at all to do with the cars not meeting federal standards?

And why were those MM tags used, on the other cars in the GM line-up?
Cadillacs, Novas, Rivieras and Impalas?
