in the sept 2008 chevy high performance magazine they did an intake/cam test,on a sbc 383 with 10.5:1 cpr and brodix IK200cc heads and a couple of comp cams solid roller cams and a 750cfm holley carb, keep in mind the single plane intakes used a more radical cam than the dual planes were tested with, and the engine combo they used is unlikely to match your so the results on your combo are sure to differ, but its still rather interesting to see the differances an intake makes
, BTW they DID test the EDELBROCK DUAL PLANE intake with the larger cam, that the single planes were tested with and and the EDELBROCK single plane with the smaller cam the dual planes were tested with

The rpm air gap seems to do very well in all the dyno test efforts I've seen published.
