1969 BB 4-speed Barracuda Formula S

Intersting thing when looking at underside noted that the Torgue boxes are filled like the sixpack and Hemi cars tho I have seen this on newer dusters in the 71-74's. Is this norm because it was a Big block car?

Not sure what you mean by "torque boxes filled"? The rear torque box you show is the normal one used on these cars. Does it have the front torque boxes?
