360 oil pan problem
I think there is a difference between the 360 magnum and the 360 LA oil pans.
(just like there is a difference between the, torque convertor balance weights, for both engines), even though they are both externally balanced engines.
Check this out at Mancini. You might want to call them.

As you can see the" Mopar" gasket numbers are not the same for the ( 360 and R blocks), and the (360 magnum).
Hope this helps.
