Using a converted auto engine (planning on a stroked 302 ford), in initial planning I was thinking I should go with a rear sump as you are more likely to be nose high than nose low. All of the larger capacity aluminum oil pans however are front sump, and front sump would actually fit better with the fuselage structure.

So, using a 7 1/2qt sump does the location really matter? I have never had any oiling problem with a small block Ford in a car, and those are only with a 5qt sump.

Also, I note that the sump on our O470 is pretty much flat from end to end. Any opinions?
