oiling mods for dummies

Try this link to modify LA oiling modification by Herb McCandless from the 70s or 80s. http://www.moparchat.com/forums/archive/index.php?t-103826.html
He also has one for big blocks and hemi's. The mod improves oiling to the crank, I've done this mod myself, you need to buy 2 8"-10" drill bits. So for $30-$40 you greatly improve the oiling system on these engines. If the link doesn't work google herb mccandless oil mods and it should get you there also, or call them to get the information.
