I have a casting for the bottom of a 5 main set up for a Modal A engine. Its been heat treated and that's about it, you would have to finish machining it and add the other mains to the block. This also acts as an oil pan and, you would just plate the bottom if you were dry sumping it or build a deeper sump if you wanted. This was left over from a project I did for Modal A vintage racer. It was made using Pete Ardema's pattern and cost more to make than the $250 I am asking. Its heavy and shipping is your responsibility. Tony
