Identify oil pan capacity?
 

1975 F250 460 w/high capacity oil pan/pump.

How do I know what the capacity is of my oil pan? My dad owned it before me and knows it is a high capacity pan and pump. Are there some identifying marks or numbers or something that would tell me or is a high capacity pan going to be the same for all 460 blocks? I am going to do the oil change and I want to be sure I add the correct amount of oil.

Thanks.
