Oil pump swap necessary?
Having something fall into the pan. (It happened to me) Stuff a rage in there so if something falls it won't go into the pan. Other than that, just make sure that the o-ring doesn't get pinched when installing the pickup tube. Get a new o-ring from gm also b/c many times the old one will not be perfectly round anymore.

Same chain,same pump.)
