Blocked oil pickup or worn big ends usually.

Check to make sure the harmonic balancer is ok, I would have thought if you had a bearing knock you'd hear it more when warm not just on initial startup.

Are you sure it's not just lifters ticking while oil pressure builds?

I'd chuck an oil pressure gauge on it and see whats actually going on before it does any more damage.

When my bottom end bearings were trashed it would knock on start up but then get progressively worse as it warmed up.

I've heard a knock upon startup before and was timing related.

Could be a worn cam bearing too however these usually have more of a rattle.
