New to the camaro world, would it be possible to have a 396 SS with an open rear end ? numbers match on the motor and trans, date codes on axle tube are good for the build date. Ratio is 3.07

Yep, it is possible. 12 bolt was required with the 396, but posi was not required. My car originally was a 3.73 open 12 bolt.

Now if your car is a true original L78, in my opinion it probably did not originally have a 3.07 open rearend. But I could be wrong. What transmission does it have? That could make a difference.

Actually most 325HP and 350HP rears were 3.07 that I have seen. And most were NOT posi
I am pretty sure in his second post he said it was an L78 - 375 hp version. I don't think 3.07 would have been the standard in that case, but I could be wrong.

Does anyone have a listing of the 1969 Camaro Power Teams Chart for reference to this thread?

I am also looking for the one from 1968 so see what a 3.73 open 12 bolt rearend might have been standard with.

For 1969, posi was only required on 3.73:1 and numerically higher gear ratios, so an open 3.07 is very common.

My 1969 Power Team chart does not show the 396/375 engine so I don't know what was standard, but 3.07 open does not sound right.
Is the engine numbers matching?
What trans?
