1928 Oil Pan

[34Pietenpol]

I have a 1930 engine in my 1931 Mail Truck with its standard oil pan. I gave an excellent 1928 oil pan with its large flange drain hole. Wondering if using the 28 pan would be advantageous regarding oil changes, cleaning gunk, better access. Also, wondering if there was a reason other than manufacturing cost for changing to the small plug pan? The Mail Truck will always be my driver so I’ll use which ever pan makes its maintenance better/easier. Thanks for any advice!
