69 Yenko 427 Nova Question

[bbdon]

I have seen Broadcast sheets for a few 1969 SS Novas, and none of them list an SS option. Looking at the assembly manual, the instructions for L34 and L78 point to the assembly instructions for L48, which call for the SS trim to be added. Note that I am not trying to say anything specific about the Yenko in question, since I have never seen it in person, and there is always the possibility that it was not built per the usual rules. But per the normal process used at the time, any L78 car would get the SS trim, and no Z26 code would have appeared on the broadcast sheet. But I have seen a 1970 Nova broadcast sheet with a Z26 code, so go figure. The broadcast sheets that I have seen are all from the Willow Run plant. These sheets were small, and did not have many spaces to list option codes, so I will conjecture that they were not listing some redundant codes to leave more open spaces on the form.

You can see pics and read some history on the car at Kevin's site. They claim it was the first 427 Yenko Nova so maybe Yenko just pulled a non SS car off the lot and converted it although they do say it was a 396/375 car. If it was built as a COPO 396/375 you would think it would still have the SS trim like the COPO Chevelles did. It would be interesting to see what the rear end code is - if the original one is still in the car. He has a fantastic collection of cars. Does he have an e-mail address or someone who will answer some questions on the cars?

You can Email to that site and Kevin will recieve it. Go to the home page and email the web page designer Dennis Gilbert. I believe the mail gets forwarded to Kevin. Or if you look at the cars for sale page his # is listed.

I have, without luck in the past, tried to send to the web page e-mail but will have to try it again. Another thing about the possibility of a 1969 COPO Nova without SS trim - I believe the 1968 COPO Nova TH400 cars came through with the SS trim. Ray M's car has them and the red Harrell/Gibb COPO Nova TH400 race car appears to have them.

In speaking with Greg Joseph a few weeks ago regarding this particular car, he apparently was misquoted by the magazine when they claimed that he thought the car to be a COPO 427. The Otis 'crew' felt that the car was a COPO 396/375hp non-SS car. They felt that the broadcast sheet should have had a designator for the SS package, (RPOZ26 or Z27 I believe). This broadcast sheet did not have such a code, and when the car was found it did not have it's entire SS ornaments. The final result is that they felt the car was a non-SS L78 car, which could only be explained by being a COPO. They did not feel that it was a COPO 427 car, the magazines were much more eager to make that claim and print it under someone elses name!

It is one of the few cars remaining out of approximately 30-37 produced by Yenko in '69.

Wish I coud find one!!

On Yenko's order form for the '70 COPO Novas he inadvertently wrote COPO 9020, then crossed it out and wrote 9010 - which is correct for the LT1 option.

Does anyone know what COPO 9020 was for? Is it possible it was for L78 non-SS Novas in '69??

I have not heard of a COPO 9020. The 1969 COPO's were 95xx numbers like 9560=ZL1, 9561= L72 Camaro, 9562= L72 Chevelle, 9567= ZL1 prototype Camaro. You would think that if there was a COPO 1969 Nova it would be a 95xx number. Chevy did release service info on the 1969 Camaro and Chevelle COPO's (see ED's book) but did not include anything on a '69 COPO Nova.

JoeC:
I thought about the 95xx vs. the 90xx, but then I remembered that the 9737 was from 68. Maybe GM was issueing COPO #'s in a decreasing order? Just a thought.

The numbers are all over the place. I don't see a pattern but maybe someone else can. Other COPO numbers;
9738 '68 Nova L78 TH400
9796 '70 Camaro Z/28 new design big spoiler
9568 found on a '70 Chevelle with spec paint build sheet
9011 or 9711 (not sure) for the '71 Yenko Vega
Did the Stinger Corvair have a COPO number?

According to Ed Cunneen, It was believed that the Corvair Yenko Stingers were ordered under COPO #9737.
