Aluminum Intakes - What are You Running?

The LD340 is so close to the air gap, that Edelbrock used to only recommend switching from an LD340 to a Performer RPM or Air-Gap in the case of fitment issues. I've read somewhere that the LD340 was used in the development of the RPM and Air Gap intakes and the only real difference between them is the RPM has less flow spread from port to port than the LD, but the LD has a marginally higher overall average flow. If you have a serious build and want it to act like a single plane, get the divider milled out by the MP directions and add a one inch open spacer.
