D4B DC mods like the LD340 DC mods?

Would it seem logical that what's good for the LD340 is good for the D48 or LD4B in regards to the Direct Connection plenum mods? I don't know the exact spec but I'm talking about the square notch.

For those that care: 1965 273 2-bbl. Changing to dual point distributor, D4B, Carter AVS 4638SA (1969 340 auto), Commando type cam grind. I will probably keep the 9:1 (?) pistons for now but if it gets opened up you know the 10.5 pistons will go in.

So, from a flow and distribution aspect is what is good for the goose also good for the gander?

Having done the DC mods to a LD-340, I would not do the mods to that intake unless your really cranking up the power with a large cam of at least 248@050 and .575+ lift.

If you’re “Going There,” go for it. Otherwise, leave it stock.
Go to a RPM instead and then add a spacer for more plenum if need be.
