2009 387 Peterbilt Motor mounts / ISX 871

[Nostalgic]

If I remember right, there was only about 1/4" clearance with the top of the frame rails when dropping the engine in.



If your 387 is anything like the 386, the driver side is just plain misery. A pile of air and electric lines runs right over the mount, and the starter is tucked right in the mess.
