When it comes to auto racing, there is an old adage that states, “In the constant pursuit of a quicker elapsed time (ET), a faster mph, or a consistent part, evaluating never ends.” After a recent Hughes Engines’ test in Mopar Connection Magazine comparing single- vs. dual-plane manifolds, we wanted to perform a “real-world” drag strip test. With a single-plane currently installed, we needed a dual-plane for our 340 equipped Dart, so we acquired an Edelbrock Performer RPM Air-Gap intake manifold (PT# EDL-7576) from Hughes Engines. Based on the Hughes Engines’ test, the Air-Gap should increase mid-range horsepower helping to propel the Dart down the quarter mile a few hundreds of a second quicker than our current Edelbrock Torker II manifold. But would it?
