Should I swap intakes

With his set up I believe he will see an overall gain with the RPM intake . The power increase in the lower rpm ranges will more than offset the small loss from 5,200-6000 rpm.

The carburetor pad center height on the RPM is 5.35" and the Victor is 6.10". Whatever air cleaner set up he is using on the Victor should work on the RPM intake.

Agree, but neither will work on my 68 fish, w/ a 4 1/2" air cleaner. victor only if going to a small air cleaner or none at all. Am using a drop base too. Agree, but w/ a 505' stroker, a little low end loss isnt`my main concern.

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.

With a car as heavy as urs, a set of low flowing heads like urs, and that small of cam and carb, I agree, the rpm would probly be best.
