Default Build Sheet axle ratio codes

Anyone have a reference which translate them all for 1970?

Based on build sheets submitted to the registry:
GV2 = 3.08
GV4=3.36
GV5=3.36
GV7=3.55
GS4=3.70

I've also seen some references to 3.71 instead of 3.70 on the build sheets, but as you know, they are often difficult to read. What is the code for 4.11 & 4.56 and 2.73? Are there any other build sheet codes? ~Juliet

Hi Juliet, This may help.
It's from a Corvette parts manual.

Thanks Barry. I presume this list is not just corvette though. Do you know what years it covers? ~Juliet

Hi,
The manual covers 1953 thru 1978. It also says "effective date" Sept 1977.

Although it's a Corvette manual, it appears to have all the Chevrolet, or GM codes listed.
There are five pages of codes listed.

If you want all five, just let me know and I will email them to you.
Barry

Thanks Barry, The only one I can't find is 3.55. Maybe you can just skim over those other pages and see if there's a code listed for it. Also, what is the name of the publication the above page scan is from? I would like to cite it on the registry website as the data source. http://corvetteforum.net/c3/1970registry/codes.html

Thanks a million!, ~Juliet

Juliet, here is a scan of the cover.
I couldn't find the code for a 3:55 ratio.
I called a friend that works at a Chevy dealer and he thinks he has
some old order books at home that may have the code.
He said 3:55 ratio has been obsolete for quite some time now.
I'll give him a call at home tonight.

It's interesting, that those codes that I posted earlier are currently still used by GM when ordering a vehicle.
Barry

Juliet, I used Google to do a search and found this at the top of the list.
It's codes for a Camero. The axle codes are likely the same for a Corvette.
3:55 is listed as G96..

Check it out here http://www.camaros.org/options.shtml

Another site, however I don't see 3:55 listed. http://www.corvetteactioncenter.com/tech/rpo/rpo2.html

Look at this build sheet I have on the regsitry website:
http://corvetteforum.net/c3/1970registry/04143BS.jpg

It's from car 04143. I'm pretty sure thats a GV7 for 3.55 axle ratio. That doesn't match the camaro data. I'll check the other codes to see if they match perhaps. ~Juliet

I did a search for "axle code GV7"...
The results... All confirm, GV7 as the code for 3:55
