Ok, I got it. The engine that came out is a 53 block with a knock in #6 cylinder and I'm going with all the negatives about that engine. I have a fair amount of money stuck in this 01 motor. O ringed the head, head work, injectors studs, and more. I realize it can be switched over to another short block. But I would have to buy a short block and probably have to rebuild. What a idiot I am.
