intake swap test

[grumpyvette]

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

NOTICE HOW THE LARGE CAM DUAL PLANE, COMBO DID VERY WELL

[Mike C]

I read that article with great interest. The two cams they chose are on either side of my Comp 280SR (236 @ .050, .540 lift). Currently I am running a Victor Jr. with a 1" spacer, and if I was confident I could have their results, I'd jump on it. I run a 1040 cfm Barry Grant Stage III Holley that I got long before the Demon carbs came out.
