Retrofit 5.2 in a dart: oil pan

Wouldn't matter if it was a 5.9L. They use the same pan as a 5.2L. When Chrysler changed to the Magnum engines they kept the rear main O.D. size the same on 5.2's and 5.9's unlike the earlier LA engines which are different size. I know guys have put magnums in A-bodies so their must be a pan to fit. Since you tried the pan off your 318 and it didn't fit maybe a center sump pan off a older 360 non-magnum engine will fit??? Was the O.D. of rear main size the problem why the 318 pan didn't fit? If the pan opening for the rear main cap was too big on the 318 pan the 360 non-magnum engine pan will probably work. If you find this out to be true PM me as I have a good one I will let go cheap. You'll also need a different pickup tube for your oil pump which I will throw in. Do some more research though cause I'm not positive and wouldn't want to sell you something that may not work.
