The priming of the oil before start up is most important. . At the very least, disable the ignition and run it up w/ the starter motor. .
Back in the boneyard days I used to flash up a lot of motors that had been sitting for years. . I used a drill and the shaft I cut off an old distributor....it worked a lot better than bouncing a cut off screwdriver or whatever else around down in the oil pump drive. .
Buicks and other motors w/ a front distrib/oil pump and rear pan pickup were the worst. . With such a long way for the oil to travel, if you didn't prime them first you'd often get a knock....always not forgetting to check for cracked flexplates on the Buicks of course. .
Make sure you confirm distrib/pump rotation and wind down the drill speed before priming. .
