1967 Chevelle SS396 Cowl Build Tag
The next place that you are going to want to check on a 1967 Chevelle SS396 is the cowl hood. You’ll be able to tell if the car is authentic by checking a few items under the hood. There should be five lines of code on the build tag that you’ll want to look for. These lines will denote that the car was built in Atlanta, it should say “13817” for the SS396 body style, and “729-A” will show the medium blue interior (via Motor Trend).
Another code that you’ll want to look for is”Q” for the Muncie M21 four-speed manual transmission. This was the specific transmission that was used in the SS396, and without it, the car wouldn’t be authentic. With these things in mind, you should be able to decipher whether a car is a clone or an authentic SS396 model.
