Damn good info

Almost forgot, supposedly a 5.2/318 Magnum rear main cap is externally machined the same as a 5.9/360 Magnum, so both of them accept LA oil pans.

The Magnums used much better one-piece oil pan gaskets that can be used with a Magnum timing cover and accessory drive serpentine belt setup, but the Magnum gasket also works well on the LA timing cover with a little extra silicone in the gaps at the front. I have a Milodon LA 360 oil pan on an LA hydraulic roller block. The front oil pan seal holes in the Milodon pan were so far off I could not use the LA gasket setup at all, but the Magnum gasket sealed up nicely.
