The Sonoramic Commando Intake?

Longrams and inline dual fours were available on the 383. They were not left out.
It is just evolution why the 440 didn't get the longrams. They came about to late(66)
Longrams were 60-61 technology.

Thast explains it then. I thought the 440 was made earlier in the time line for Chrysler, I didn't realize it was a late bloomer so to speak.....So really, the early "B" engines as well as the early RB engines came with or could be had with the long rams and then what? '62, were discontinued?

Thanks guys, trying to make some sence of things to understand a bit better on why this or why that on how Ma wanted or things happened at the Mopar factory....
