I have a new Holley mechanical fuel pump part# 12-834 on my SBC 400 engine and when it first starts the fuel pressure is at 6psi and drops down to 3 psi and below I'm cranking engine from a jug of gas to the fuelpump I removed the pump and it says made in Korea WTF can the fuelpump be bad right out the box?

3psi is more than plenty at idle. Anything above 1-2 at idle is plenty. At 6000-7000 rpm's is a different story.
I'd say run it and see what happens when you crank it up.
