Cummins 8.3 variants

[ScubaCat]

Are is the eine essentially unchanged from one application to the next? If not, what's different between them? They used it in MV's, RV's, construction equipment etc etc....I found an engine at a very reasonable price but want a rebuildable core that will be a direct swap.

Anyone know anything that can sort it out?

The long block should be the same. This means block, head, and internals. All the bolt on stuff will be case by case but can be swapped.

Anyone have a clear pic of the exhaust manifold so I can compare the two pieces?
