Is it possible that a COPO order for a 70 Yenko would/could include a request to GM that the car be built with 3.55:1 gears? My car (at least according to a prior owner) may have come from the factory with dated 3.55: 1 rear end gears( as a 1 0f 3!). Is it possible to document this claim?

Several members have suggested that they were probably installed at the dealership (Yenko); but, I really don't know?

Thanks far any input.

Rick -- as far as when Mark owned the car ... I have no idea what gear was in that car back then ... just assumed it had 4:11s ... TAZ <<GRAEMLIN_URL>>/dunno.gif

Should be able to tell by the axle code. CBV for a 4.10 or CBT for 3.55.

Same location as 69. More info here: 69 Camaro axle codes. (http://www.camaros.org/drivetrain.shtml#axle)

Even the same code, except all the 70 axles have a "C" in front of the 69 two letter code. So a 69 Camaro BV axle became a CBV for 70, used on late Camaros (around Aug. 69) and the 70 Nova.
