I still have the 01 f350 but thanks too a couple of bone heads with a can of starting fluid it has a cracked piston or ring(s). I put over 600,000 miles on that truck from 2001 till 2007, since it is regular cab, 4x2, plain jane XL, I decided to make it a parts truck. the ZF6 (reman) is going in my F550 and I want to tare the engine down and see what 600,000 abusive miles + 60hp chip + amsoil equals. I would like to take pics, document it and share it with the world.
