Should fit but will be super close. I'm running one with a Holley 3310 (which I believe is taller) and using an air cleaner with a drop base (7/8" drop IIRC). ('67 Barracuda)
Get some 'clay' or lightly ball up some aluminum foil on the air cleaner stud and gently close the hood.

As was clarified before, the LD340 is not an aluminum copy of the stock intake.
Some version came with Chrysler part numbers - and for class racing - they were legal - and by following the guidelines in the bulletins they worked well.

The big runners lose velocity at low rpm relative to stock, or LD4B, and most likely one reason why the new "RPM" are better for street and building torque earlier at WOT.
