This sound like a rod knock, if the sound is coming from down in the engine. Should have the oil pressure checked, and another opinion since I can't be there to listen.

That's what I have been told but it has been fully overhauled professionally the engine doesn't even have its first 500 miles on it yet

But if it's a rod nock then what can I do to fix it??

Then who-ever rebuilt it is who you should be asking. There should be some type of warranty, or a private party should stand behind their work. It could be a loose torque converter for all I know.
