That is a totally
logical thought. But from what I heard, they used the same cam for 1957 Super D.
Don’t know about
1958.
The logic here could be
that the double setup being progressive (with even less cfm during normal
operation!, when only the rear (smaller) 4bbl is in operation), the shifting
point is raised (easily done, with the rod connection), which makes the engine
rev higher, needing more air/fuel mixture. About half-way throttle the second
(front, bigger) 4bbl joins in. Both secondary’s are vacuum/contra-weight
operated.

500 SUPER OPTION, QUESTION.
It would make no sense to
add 650 cfm of fuel mixture over a single 4 and NOT jump the cam up to meet it.

SUPER OPTION, QUESTION.
Let see how knowledgeable the gang is on Dodges?
If you
ordered a 1958 Dodge Custom Royal with the D 500 Super Package which comes with
2/4 bbl carbs, is there a difference in the camshaft of the 2 /4 bbl
engine and the 1/4 bbl engine. Is there any other difference other than
the extra carburetor?
(The
answer is not that you
get a different manifold and one more air cleaner)
