What are the rear end ratios on a 1976 nova 6 cylinder automatic transmission?

There wasn't a single rear end ratio for all 1976 Chevy Nova 6-cylinder automatics. The ratio depended on several factors, including the specific options chosen by the original buyer (like the engine size, though you specified 6-cylinder) and the manufacturing plant. Common ratios included:

* 2.73:1: This was a fairly common ratio, offering a good balance of fuel economy and acceleration.

* 2.56:1: This was another relatively common ratio, biased more towards fuel economy.

* 3.08:1: Less common, this ratio provided better acceleration but at the expense of fuel economy.

To find the exact ratio for a *specific* 1976 Nova:

1. Check the Vehicle Identification Number (VIN) plate: While the VIN itself doesn't directly state the rear axle ratio, a decoding service (many are online) can use the VIN to access build information, which *may* include the axle ratio.

2. Look at the axle housing: The ratio is often stamped on a tag or directly on the differential housing itself. You'll likely need to get under the car to see this.

3. Check the owner's manual (if available): The owner's manual might specify the axle ratio.

Without the specific VIN or a look at the differential, it's impossible to say for certain what the rear end ratio is on *your* 1976 Nova.
