Yenko 73 Camaro?
 

I posted over on the Motion forum that I seemed to remember an article about a 73 Camaro that was a shop test car with a mild 400 small block in it. It was suggested that I might have been thinking of a car that Yenko built. I read the article decades ago and it was old back then. Does this ring a bell with anyone here?

Rich,
this is the article I was talking about.

The writer saw this 400 cu in Z/28 at the GM proving ground.

the article says that it was going to be Yenko's new "Super Z" 400 Camaro and he was "taking orders"

That article is the one I was thinking of when you mentioned it. I could see that picture in my head, but couldn't recall where. Thanks for finding it:)

That's the one. Thanks.

I wonder how many were made and what the option cost. I seem to remember the ad saying the car had a/c but that wasn't available on a Z in 1972. The 73 z ran the quarter in about the same time as the 70 Z and the 70 had over 100 more HP and steeper gears. I wouldn't doubt that this car would have went deep into the 13's Pontiac's Super Duty Firebirds ran 13.50's with 290 HP. Who knows?

hard to say what Don would have built for a 1973 Yenko COPO 400 cu in Camaro but we can use the Yenko Duece as an example.

A mystery SS350 360hp Nova showed up at the 1970 Chevy press pre view where the press was allowed to test it on a drag strip and a road course and it was well liked.

Don was able to get it for the Deuce.
Yenko did a COPO order to get a non SS Nova with the LT1, 4sp and TH400, F41, 4:10 12 bolt posi, PDB, base interior and other items

He was able to get a custom made 4sp Hurst Shifter installed on the line (that was amazing), and ordered a column shift TH400 then dealer installed a Hurst Auto Stick floor conversion shifter.

He added a hood tach and his own design stripe kit and other options


For the 1973 Yenko Camaro, he may have got the COPO 400 cu in Camaro and ordered it as a non Z/28 with F41, 4:10 12 bolt posi, PDB, base interior. ft and rear spoilers, a 70 71 Hurst shifter (Camaro did not use the Hurst in 73) a TH400 option with dealer installed Hurst Duel gate shifter, and other options he liked

possibly a COPO for a wider tire like he did on the Yenko Chevelle

possibly a COPO for larger sway bars like on the 1968 COPO Camaro

possibly a COPO for a Magnum 500 wheel or some other GM wheel

maybe a hood tach and gauges or something else from Dixco

add a Yenko design stripe package

We can only guess
