I have a 2000 3500HD cab & chassis with a dump bed that has a trashed 7.4L. Nothing really salvageable but the block so gave it to a kid I work with who wants to build it for his project truck. Believe it has the 4L80E transmission.
For a parts truck I have a complete 2006 C6500 with the 8.1L and an Eaton 6-speed. Trans is junk but the engine runs good. Was toying with the idea of swapping this 8.1 into the 3500HD. Would probably want to stick with the auto as nobody at our company can drive a manual without destroying it.
Wondering how feasible of a project this would be. I'm imagining needing to take most of the ECM and harnesses off the C6500 in order to get this thing to run in the 3500HD. Guessing I might be splicing together a lot of harnesses. Not sure if the 8.1 would have a different flywheel housing since it had a med-duty Eaton trans (FS-5406A iirc). Thoughts?
