How to turn a motor over by hand?

I've been working on building a motor for my very 1st time. It's about 95% done & I'd like to turn the motor / Rotating Assembly over to make sure everything's working right.
From what I understand I can turn it over by the Crank Bolt.
Does the motor have to have oil in it before turning it over ?
I used assembly lube all through the build so I'm not sure if I have to put oil in it before turning it over.
Please let me know so I can check it out this weekend. Thanks !!!

You can rotate it without oil in it if you used lube during the build. The oil helps with heat as much as lubrication.

Just remember that every time you turn it over you'll need to make two complete revolution's to keep it in time. Unless you've already put the distributor in and marked number one on the cap.

I kind of want to turn it over to find TDC of the #1 Piston so I can put the Distributor in.
I'm hoping this is possible using a depth gauge in the #1 Spark Plug Hole.
Going to check my Chiltons on finding TDC before doing it though.
Thanks for telling me about the 2 Revolutions. I didn't know that.

just remember that even on the exhaust stroke, air will blow out of the plug hole and the dampener will be on 0

So...How do I know When the Piston is in the right position on the right stroke so I can install the Distributor ? I had the Block Done & Assembled at a shop so I have no idea what position things are in. I'm guessing I can tell somewhat by the Marks on the Har. Bal. ???

You could call the shop and ask if they left your engine in time. And if you haven't moved it it should still be there. But to be safe all you need to do is take the valve cover off on the number 1 side of the engine, put the right size socket on the crank bolt, you'll need an extension. Use a breaker bar or a good size ratchet. Watch your intake rocker arm while you turn the motor clockwise and when the intake rocker arm goes up then back down, which will close the valve for compression, the next time 0 comes up on your Harmonic Dampener you will be at TDC on the compression stroke. You can tell which rocker arm is intake by looking at the intake runner. It will line up with the intake rocker or valve. look at you exhaust hole on the side of your head and it will line up with the exhaust rocker or lifter. The intake rocker should be the very first one on the front of your head.

Follow the steps in the link below.After you pull number 1 piston up to tdc and drop the distributer in until it bottoms out on the block,the rotor button should face the same direction as the green line(shown in the second picture on the link below)So the rotor should point towards the number one spark plug post on the cap & the "0" mark(located between the two 10° marks)and timing pointer should be aligned with each other.After you get it setup this way,remove the spout plug(from the TFI module wiring harness) start the car & let it idle while you start turning the distributer.If the engine is idling so low that it is stalling,rotate the distributer a tiny amount in the clockwise position (which advances timing)Once the car is idling enough to continue,keep rotating the distributer til you get to the 10° mark,tighten the bolt,recheck timing to make sure its still at 10° reinstall the spout plug,you're done.
