Superstock oil pan for 340

My Duster is a low compression 340 SS/JA car. The car is actually a 75, dressed as a 73 to run the 340.
Awesome !!! Thats right 75 would have been the low compression 360 , I actually had a 73 340 Duster back in the late 70s it was a street car though. If you don't mind me asking who's car was it before you acquired it?
