Yes, 366 and 427 tall deck dist's are same length as small blocks and big blocks.
IF, IF you use spacers on a tall deck engine with a conventional low deck 396, 427, 454 intake you need a dist. with a movable collar, to correctly place dist gear in correct place on cam gear.
There's some other weird stuff like the earliest small blocks had a different passage setup, that's the channel at the bottom of the dist housing, just above the gear. The first year or two of the tall decks were gear to gear timing setups, no chain. The dist gear was obviously different on these...
There are a few more, but they are REALLY odd and not common
348's and 409's are cool engines, but I'd want to have a bunch of extra parts for them, if I was running one. Some of the every day parts for them are way hard to find.....
