My son is putting a 360 in his '72 Dart and we were wondering about the differences in the dimensions of 318 and the 360 oil pans.  We had herd that the 360 seals were bigger, and we also herd that the seals were smaller than the 318.  Any help on this would be appriciated.  

Front and rear pan seals are larger on the 360.
Other then that they are of the same dimension,just the seals at the ends.
Center sumps are all the same truck/van pans rear sump front sump ect,
