Re: Rear End ?

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.

68 Camaro SS 396 - 468 BBC now, M21, 12 bolt 3.73 coded housing but w/ 3.31 gears.

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.

Yeah, those "low HP" 396/325 and 396/350 cars had a standard ratio of 3.07 open.

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?
