rotating a keyless crank

What are you guys using to rotate the crank when the crank hub is not on? I've got an old crank socket, but the key is missing on LT1's.

I can and but i would prefer not to, because when it comes time to install the timing cover i'm gonna have to rent a puller again.. I'm thinking of getting a crank key and temporarily using it so i can use my old crank socket? anyone do this? What size crank key should i be looking for?

If you get a key, you might as well take your stock hub to a machinist to be cut for it as well. It will be dirt cheap.

Makes no sense to install it just to turn the engine over and remove it again.

Use the stock bolt and washer, and a 1/2" drive socket as a spacer. Be sure the plugs are out. You can only turn it clockwise.

Sounds like he's saying to get a socket big enough, like a 1/2" drive socket, to cover the threads of the crank bolt and space it out so that you don't damage the threads.

Wouldn't that weaken the strength of the bolt? having less threads grabbing the crank instead of more threads?

Use you're best judgment, obviously you wont be using a deep set socket. Also with the plugs out it will turn over relatively easy.

I just put a few washers on the crank bolt so it doesn't bottom out before turning the assy. The torque spec on that bolt is something like 75ft lbs. If it takes that much force to rotate your assy. then something is wrong.
