pretty sure STRD gets there own engines. Thy go to Japan and pack there own containers like me. Not sure how he sources the parts tho. These engines are cheap for many reasons. They are much cheaper than what the exporter even paid for them. Its mostly to do with drug money and other countrys. not going to explain it in detail cuz I only know the just of it. But ya get as cheap as you can get. Its normally a 50/50 draw anyways cuz most those engines have been sitting well over a year.
