As to why 413-426-440 RB engines are referred to as tall deck and 350-361-383-400 B engines are referred to as low deck..and yes 2 distinct different intakes...

different distributors too
Not dumb at all. You won't know till you ask.
Deck for B engines - 9.980
Deck for RB engines - 10.725
The taller deck height engines (RB which means raised block or raised B engine) must have a wider intake. Since the decks of the taller block are taller, they are also wider apart.

yep what they said...
Not to muddy up the waters, but they did make a RB 383. I had one, 1960.

Unless you are using an Indy Max aluminum block....than they both, b & rb, take the tall deck dizzy....or so I was told by a member here....

True...rb version is longer shaft than b engine distributors,and yes they did make a rb version of the 383,think only 1 or 2 yrs and think 59-60yrs..pretty rare to find one and apparently not popular or special....
That's why I did not use engine sizes. Just B and RB. lol
