Are these 8 quart pans? They came off my 454's that are now stroked to 496.

I didn't have clearance issues, will I have capacity issues???

I'm building the same motors and have the same questions will my stock oil pans work?

most steel rods will clear stock pans with a 4.25 stroke crank...but ck by turning engine over before bolting the pan on

My steel pan cleared with no issue. I think it will come down how far the baffle sticks up.

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.

A good pan is cheap insurance!

I'd buy an 8 qt. at the minimum. Get a nice baffled pan made for offshore conditions.

Forget the windage tray and use a crank scraper.

Whatever you do, dont buy a Canton pan..... I ran them on my stroked 496's in my old Scarab. The oil pressure was fluctuating all over the place above 4000 RPM. Made One change, bought 2 new Gil pans and the problem was solved.
