Anybody know whats the best way to store a crank, is it better to stand it on end, suspend it or lay it down? I have them on end right now but thought maybe there's a correct way. Thanks

Best way? In the block.
Other than that I was taught at school to stand them up.
However, I've see them laying down at several machine shops.
Call a crank manufacturer.

i wonder if it really matters..i would worry more about humidity/rust/dust...if it distorts on its own weight,i dont want it....jmo

+1 (They take up far less floor space standing up.)

Coat it well with cosmolene or some other anti-corrorosion material.

Make sure you stand them up out of the way. I had one come down across my leg and took 15 pieces of thread to close the gash in my leg.

They can fall over break a foot, a toe, they do not balance well standing on end.

They do not bend from sitting.

Bolt a flexplate to it so it cannot fall over when stood up

Id be more worried about the damage to the crank from falling over when standing and hitting the concrete or something else than laying it down on its side for storage?

spray it down with some fogging oil and place it in a plastic bag and stand it up..

At Raylar we heavy spray for rust prevention and hang them in a rack for crankshafts. In your home or small shop the same rust prevention is necessary and an old balancer makes a nice stand to put the snout in and store and also tends to keep the overall diameter protected from bumps and bruises.
