It looks like the Edelbrock LD4B has smaller runners compared to the 340 intake I am using now.

Yes, it does.

As I understand it, the reduced volume would increase velocity and thus torque, is that correct? Any idea how much gain I would be looking at? Thanks.

Yes, that is correct, you'll probably look at 20 lbs. as a ruff general guesstimate.
