With a fly wheel attached and the spark plugs out, turning the engine with a screw driver on the starter ring works. Turning the damper pulley as suggested works as well. If you have oil in the pan, and the dizzy out, you can turn the pump and provide oil pressure to all the moving parts. If it is a new rebuild, it will drag a lot. New rings have some friction and a honed surface to seat against. Times 6 so don't be surprised if it takes some real torque to move it. Use the holes on the damper pulley and a strap as recommended above. Make an adapter for the hand crank if you have a pulley that supports it. Use a screw driver on the fly wheel and the bell housing if you can get to it. If you don't have an oil canister hooked up spinning the pump will make a mess. If the line to the oil pressure gauge is open you will have a mess...I am certain I have missed some warnings so take care. Opinion ahead. On any engine that has sit, been just assembled, Or had a major repair, I like to turn the oil pump, with the valve cover off. You can see if oil is getting to all the rocker arms. I like to turn the engine over and watch each rocker arm and valve move. Seems like cheap insurance to prevent a bent push rod or sticky valve from escaping notice. Just my 2 cents.
