The 440 source pan is still a good choice. Milodon has a similar offering with an anodized finish if you prefer. Available from Summit, etc. If your engine is apart then you might want to use this opportunity to have your machinist open up the block to use the Hemi-diameter pick-up tube. Regardless, make sure that you buy the pick-up tube intended for usage with your new pan.
