It woulld be good to prime it before start.
Theres basically 2 ways you can do this.
1) remove the dist and use an electric drill w/a cutoff long straight slot screw driver head. Engage the screw driver into the oil pump slot then spin away.
2) remove the aprkplugs and depending upon your truck/engine model, either don't turn on the ign or remove the coil lead and use the battery to spin the engine until you see some oil pressure register on the gauge and/or see oil comeing from the rockers.
I used method #2
Good luck
