Tim, no lies here. The springs were seat tested for pressure. I don't recall the exact spec but it was in the 50s. The crank is a moot point. Shit happens. The bearing wear was what lead to the comment about clearances. The first motor was handled by DuramaxTuner. It broke a piston with almost zero miles after the motor was in & out for a no start issue. DT did not do any machine work to the block besides align hone. Then my cuz wanted it to go to Merchant, but DT Nick refused and sent the whole truck to DTS. This was after he paid DT for the twin kit, motor parts and labor. After the truck was done at DTS, my cousin also paid David 13k for his work. He has the receipt. A lot of stuff was hacked on the motor. Piping rubbing, lines rubbing though wires, etc. Just looked like a rush job to us. I do think he was over-charged for labor and the ported heads that were bone stock. I don't really have a dog in this fight, but I stick up for family/friends when I think they were wronged. I'm not here to argue about stuff, just warn people to stay away from what I consider a bad shop.
