Should I swap intakes

RPm intake is awesome, yes

Bigger carb for a 440, yes

Vacum secondary's for a street car, HELL NO. Age old myth created by people who can't tune or drive a car.

From 1981>1987 drove nothing but 750/850DP's on the street with my '71 340- 727 s-strip car, was awesome, VS carbs were a major loss in performance and lasted 1 day on the car with plenty of effort to tune it. Same with my 446ci car.
