318 stroker oil leak :(

At this point i have to agree with the pan diagnosis. Still don't understand how it seemed so widespread before?
I assume you took the pics from a hoist. This might sound nuts, but if you put 2-3 extra quarts in it and tilt the engine rearward and see if you can locate the spot it's coming from. From what i've seen so far it should be pretty obvious. If it's not i have to wonder about a crankcase pressure issues.
