Drag pak intakes are available, but you have to order it to get it (they aren't kept in depot stock).

Really for carb, the 392 crate carb intake was the one. Same as DP manifold but no injector machining, etc.

There should be an $800 distributor conversion coming shortly, it's more expensive than a distributor for an older engine because a new timing cover comes with it.

No timeframe for 6.4 yet, the desire to make it available is strong but I wouldn't embarass myself taking a guess at eta yet.
