Is this in an A body?
If so, what you have is an LA 360 oil pan on a Magnum block (Magnums never came in a passenger car, so using an LA 360 pan is how it's done).
An LA pan has 2 notches in the front seal area (red circles), the Magnum pan does not have these and is completely round (smooth).

The problem is when a Magnum seal is used, it does not fill these notches and the voids that are left will piss oil like Jed Clampett's backyard.
The 2 most common fixes for this are:
1.) Use an LA 360 oil pan gasket set.
2.) Use the one piece Magnum gasket, but when installing fill the voids that are left with a generous amount of RTV Ultra Black or Gray, let it tack up and then install the pan.
And by the way, the pan won't just drop out after dropping the center link. You'll have to at a minimum unbolt the motor mounts and jack the engine up, drop the starter, possibly unbolt your exhaust or headers, and disconnect or try to move your transmission cooler lines if so equipped- maybe more depending on your car's equipment...
