Internal design, shorter can with the 47e. Both will work fine. Champion Labs makes them and explains the design change on their website.
The PF47 is the old design filter and the PF47e is the newe OEM design. The new filter is slightly smaller and is to be used in 2010 vehicle and newer where design constraints prohibit the use of the larger PF47 filter. It is also supposed to be more environmentally friendly.

Just a quick note I found 2-AC-Delco PF47 Oil Filters they were for a 1985 Buick Skylark hope it helps.
An ACDelco PF47 is an original equipment oil filter for that 04 Impala 3800 engine.
A larger filter has more filter material can last a little longer. Smaller filters will do the same job. But have less material to filter with.
