No, it won't interchange. The earlier engines have an integral bellhousing on the rear of the engine, and this is also present on the sump. The sump forms the lower attachment to the gearbox, and also mounts the starter motor. The 8BA engine uses a separate bellhousing, with a starter motor plate.

You've obviously got an engine already, but try to have a look around for other 8BA sumps. There were different styles for different models of cars, pickups and trucks. The "Pickup" style should enable the engine to have the correct arrangement and clearances to be a direct bolt-in swap for an earlier engine.

If you can't find an appropriate sump, you can use your (or someone else's! ) sheetmetal welding skills to shorten the depth of the pan and oil pickup tube.
