I just got a RPM intake for my 440. it has a notch cast in the center divider. is that the type of mod you are talking about? I have a LD4B,it has a untouched divder down the middle. what mod is done to the LD340? only thing I have read was how they cut a notch in the rear of the divider for a 3 barrel holley carb so the rear butterfly would open(2 primary butterflys with one oblong butterfly on the 2ndary)

here is a shot of my RPM intake with a notch cast into it. so you would mill it straight down till 3/8' of the floor to remove the divider wall. i wonder if that is the idea behind the cast in notch on the rpm intake. looked my LD4B over and it is divided down the middle with no notch. so milling the divider down sort of makes a open plenum area but still has a duel plane floor in the intake. very interesting.
