I have a 6.4 engine I got in a truck that spun a rod bearing. It's all apart now. Block was checked and machine shop said it should still be standard bore after a good hone. But no guarantee. If someone is interested for the right price I can get it checked out again. Heads are complete but cracked. K16 has 2k miles on it. Crank and rods are junk. Make offers on parts not sure what anything worth. Everything is forsale
