Can you add a little more detail and try and remember we can’t see this thing we can only go by your description.
Do you mean the crankshaft will rotate without the cam installed?
Are you sure your block is a 400 cu” block or is it a 350 that you’re trying to stroke?

Rods are directional. Make sure that you don't have one, or more, installed wrong. If you don't have the heads on yet, can't imagine any other reason.

sometimes they run a smaller base circle cam in small blocks with aftermarket internals, very possible that a rod or more than one couls be hitting the cam.
If not rods could be hitting the block near the oil pan rail.turn it over slowly by hand and see where it is hitting.
