Atk motors beware

I recently purchased a rebuilt long block from spartan atk and just got it running and the bottom end is bad I believe. Not 100% sure yet but I'd bet my jeep on it. Stay away from these motors. I wish I would have

Did everything I was supposed to. Sounds like the main bearings are all jacked up. Sounds exactly what my old motor sounded like before a main bearing cap came off and the piston went through the side of the block.
