ID bellhousings with a casting number????

Ok I have received 2 bellhousings in the last 2 weeks. Working on my 833 behind my magnum retaining the factory injection. Can anyone identify these bells if I give the casting numbers?
3893728 this thing is big, full size ram, it can be made to work. Would like to know what truck it came from.
4338364, full circumference bell looks deceiving can't nessecarily tell if it will take a 143 tooth flywheel, but it is hydrauli my activated. Will also require some modification, if it can swallow the flywheel.
Thank you, Dan:burnout:
