Superstock oil pan for 340

Believe me I am in no way any where close to knowing what I am talking about I have just been a fan of Stock and S/S for a long time and read a lot about it. I do have a few friends that compete in the classes it’s always interesting to hear them talk about their combos. Like this past year it’s always great to see the Mopars do well in those classes.
I am very new to this and see now in the book that you are indeed correct, I was mistaken on this aspect. I believe my confusion came when I had an aluminum carrier housing for the 8 3/4 and realized it could not be used in stock, but was legal in super stock. Thanks for correcting this post, I certainly have a lot to learn and do not wish to be putting incorrect information out there for others. The rule book can be quite something to decipher.
