Oil pan size for 496 stroker
#5
Those look to be 6 quart pans to me. The GM 8-quart pan has a sump that comes within about 4 inches of the front. These were commonly installed on heavy trucks by GM - a friend of mine always called them the "school bus pans". Smaller pan will probably clear, but with the increased windage produced by the longer stroke, you might want to consider additional capacity and some type of windage tray. Would hate to see you have oil pressure issues after building and installing a brand new engine.
