well there are 2 different 360 pans , the LA 360 & the Magnum
I hesitate to contradict CP but I think that's wrong actually.
The LA 360 pan comes in at least three flavours with front, rear or middle sump. The middle one is for cars, the front for vans (I think) and the rear for trucks (I think).
They will all bolt up to any LA 360 block or to a magnum block but you need the correct oil pick-up for the pan. The 318 pans are different around the bearing caps and won't fit.
On the magnum 360s there are at least two pans, again with the sumps differently placed. The sumps appear to be smaller capacity than the LA ones and also differ in that they have a guide inside for the dip stick to run into. However they will bolt up to an LA 360.
I believe the 318 Magnum pans are the same as the Magnum 360s and won't fit LA 318s.
