a higher stall converter would help, with that cam I,d suggest a 2600rpm stall,
your surely in dual plane intake rpm range
and a 750 cfm vacuum secondary would work
theres always a strong tendency to over do things and try to use parts more suited to racing,
you'll be much happier if you don,t go down that route,
yes a single plane intake will also work,
but you'll generally give up more low and mid rpm torque,
if you have the hood clearance (and that needs to be checked before you order parts,) Id go high rise, dual plane intake
and take the suggested components that match your application,
as they will provide brisk performance with decent reliability.
(be sure to verify how much hood clearance you have before ordering parts)
don,t forget youll need decent headers, if you expect the intake better cylinder heads, potentially increased flow rates, too add hp, and a low restriction exhaust are required,
too maximize intake flow and allow the engine to breath.
why not call and ask the tech guys at holley their opinion also
Id be looking for a vacuum secondary electric choke 750 cfm,
but a properly set up manual secondary carb would work.
if you have the hood clearance required, the high rise style dual plane intake like the one linked too above,
tends to add several hundred rpm over the stock intake,
and noticeably better torque over most of that operational rpm range
