5/16" hex rod, about 2' long and good 1/2 drive electric drill to prime. You pull distributor out (leave wires connected, just push cap off to the side. I put a mark on the distributor housing and block to get it in right. Pull the oil pump drive gear. Make sure you note the position of the slot so the distributor tang will line up. Runn drill CCW adn pump should catch prime. I'd check oil. If it looks like it has water or gas in it, change it out with new filter before priming. You can rotate crank by hand (make sure you mark position so it lines up with oil pump gear). This will get oil through the passages in the crank and cam and up to the top end.
