COPO 9511

[mockingbird812]

So, only a solid lifter Chevy could get a 9511?

[PeteLeathersac]

Found a bit more 9511 info on this below CRG link w/ more clarification Copo 9511 was req'd to get 4:56 / 4:88 only and 4:10 available w/ RPO G84...

http://www.camaros.org/pdf/options.pdf

Note beside RPO G84;
4:10 available as the RPO alone..
4:56 and 4:88 req'd Copo 9511..
Also note under the 'requires' column is 12x37 for Coupe only
(so there goes the ragtop Copo possibilities!)..
Nothing indicating it required any specific engine so a Copo 9511 6-cylinder car possible?.

Also waaay down the page 9511 clearly notes 4:56 and 4:88 ('69 only)..


Keep digging!.

In this thread over at Steve's, there is a Document that states the the 3.55 was not available on the Nova with the L78/M22 combo. It is dated 13 Sep 1968.

1969 Nova SS Documentation Thread Cool story and a few other documents.

This is interesting...my 68 L78 Nova has the M22 with a 3.55 rear...really don't see the issue...if you could get an m21 the 1st gear is the same..?? certainly would be helpful to ahve the M22 with 4.10 or stronger gears...given what the car would probably be doing [img]<<GRAEMLIN_URL>>/burnout.gif[/img]

Please check out the post uhnder COPO USA on the DH Nova. It shows a BV coded rear that he states is original to the car.
So how do we classify this. COPO, or RPO?

Again click on this CRG F=Body chart, X cars too?.

'69 RPO G84 = 4:10 / BV
'69 Copo 9511 4:56 / BW
'69 Copo 9511 4:88 / BX

Well, according to this, if we're going to take it literally, there should be some L89 Novas. There's nothing saying L89 Nova N/A. (Big smile)

I do see what you're referring to on the COPO rears. Again, I 'd like to see a couple of window stickers that have that callout listed. Those rears are nothing special other than their rarity. They aren't like a BE which is a heavier duty unit than a BV.

That would be cool [img]<<GRAEMLIN_URL>>/[/img]...L89 Nova with a 4.88 COPO rear...maybe one will turn up now...Kwizz you around??

I feel differently and think <span style="text-decoration: underline">any</span> '69 Copo 9511 cars are indeed something special, especially F-cars and ultimately more so if an X-body!.
Again 9511 being a Copo performance option is an important part of the equation and much different than appearance options!.
Also any '69 X-body 9511 cars are real Copo Novas!!!

Yes a BE was more HD than a BV but we haven't determined BW/BX and/or any 9511 rear components factory supplied or that they're lesser to BE parts?.
Keep in mind 9511 was an available option to the BE's supplied w/ the 9560/9561 cars!.

Lets look for any '69 9511 cars w/ factory build documents/parts, again a couple of F-body cars are supposed to exist w/ authentic paperwork?.
Actual components and tube stamps shipped w/ 9511 cars will be interesting to note too as what info exists suggests the factory may have supplied some cars w/ 9511 components using BE or other stamped carriers on hand and factory 4:56/4:88 cars not always w/ a BW/BX?.

On the L89 Nova topic, I'm still a believer some may've been factory shipped but until bulletproof history/build documents show up am not convinced the head games/Pop car or any others claiming to be genuine really are?.

Back to the '69 9511 X-body cars, all seems to indicate they were built so lets find these real '69 Copo Novas!.

The 9511 should have two letters after it to designate the axle ratio and type of ring and pinion.

The 9511 codes for a Nova that got a 4.56 and a COPO Camaro that got a 4.56 would have different suffixes.

The Nova would have received a standard duty 4.56 ring and pinion set (3862527-3862515) while the COPO Camaro/Chevelle would received a 3917973 (HD 4.56)(3916230-3916231) ring and pinion set.

The same applies for the 4.88s.

I know of a few COPO Camaros that have original &quot;BE&quot; rears with
the original 3917973 (4.56) gears. Two have window stickers that have the same suffix after the 9511 optional ratio code.

Hope this helps.
