Oil Pump

That's easy

take an old drive and put a drill on it

fords have a hex if you don't have an old distributor to scavange use an allen driver or make one with a cut off allen wrench

on chevys it's a gear and you need an old distributor

to mdify to remove gear so it doesn't mesh with cam

whatever the motor just find out what drives it
and rig up something on a drill and getr done
