67 Barracuda Gen III swap

Yes, initially I mocked it up with the stock LA bellhousing to make sure everything would fit together right and to build my motor mounts.
Mock yours up before installation to make sure yours will fit without mods to the input shaft. I'm sure 408 swinger wasn't blowing smoke when he said he had to modify his. As with so many things with these cars, there are no absolutes. Mine was an early 5.7 (04), so it wouldn't surprise me if your '17 crank is drilled different- which is why test fitting everything ahead of time is critical.
Original plan for exhaust was to use Jeep manifolds, which initially seemed like they could work, but I didn't get the final fit with the clutch linkage worked out before the project took a little different turn, so I can't vouch for that. That's all I can offer at this point.
