Re: Decodeing the Chevelle
 

If that axle housing is the original,relay the suffix code to us here,as well as the Rear cast date to verify.
It didn't come with 3:55,your VIN# comes up as a January date,and that is to late anyway.
The early built got a 3:55 standard or 4:10 optional.
Once the 3:31 started around the 3rd production month,the 3:55 was dropped from the line up.
It could have received either the 3:31 or 4:10 with an M22 Transmission,but because it was built with a V01 Radiator,I am leaning towards the 4:10 posi.
Seeing as this car was built at Oshawa,check with George Z. at Vintage Vehicle Services for the Factory Paperwork showing the rear RPO code.. should look something like GY2.
Georges Phone number 905-644-4060.

I'm confused...why are you claiming new ownership of this Chevelle,while it has been receiving new bids on Ebay during all this,and has only now just expired with a reserve price not met?

Re: Decodeing the Chevelle
 

As always thanks for the info.

The Build Sheet has the GY2 so it came with the 3:31 from the factory.

I have no idea why the owner did not stop the auction...im assuming its because he knew it would not reach the reserve price but i own the car right now.

In my GM salesman handbook for 1970 Chevrolet year under
SPECIAL ORDER HIGH PERFORMANCE ENGINES
OPTIONS NO. AVAILABILITY DESCRIPTION TRANSMITTION OPTION REAR AXIL RATIOS ARE ALL LISTED. Cheque it out and I hope it will help, that is if I can scan the document so as to be able to read it
here goes.
