Latest bit worth reporting... so Mogs are slow. Gearing limited. Not only slow, but zero power. Stock for the longest time was 90 hp. That got bumped to 110 with a pump tweak. As with any diesel, to get anywhere, you need to turbo, then add fuel. The round cabs never came with turbos. It is a tight squeeze in there under the dog house. The later square cab SBU units came turbo'ed then later intercooled.
So to turbo a round cab, first up is a header. Most build some sort of log manifold, but after lots of measuring and head scratching I thought I could make a SBU design fit. Maybe. Got a backup plan if it doesn't with a bit of cutting, rotation, and rewelding. If that doesn't work, then it will be log style.
Threads are worthless without pics, so here is the parts layout. All bits are 2" schedule 40, that's 0.150" wall, 304L stainless. Thank you McMaster. Fairly inexpensive as well. Ninetys were like $12 each and the Ts were $20ish.

The mog has siamesed outlets for the center four cylinders, so only four ports.
Merge was two 90s with one leg cut in half and a T25 flange added.
