Well i have a Edelbrock 600 cfm carb and i just swapped from stock intake manifold to a edelbrock performer, now, what i'm confused about is my old intake manifold had the four holes and the spacer i have does to but this new intake has an no four holes it's all just open, i'm not sure if i should keep the spacer on or just take it out. Would air flow better? I took it to the track to see my hp improvements but nothing i'm running the exact same times, it's kinda irritating, i was expecting some kind of improvement but i got nothin, i thought maybe the spacer might be cutting the air flow maybe??? im not sure just thought i'd ask on here if anyone knows for sure!!!

Keep the spacer, it will add a bit to your low end torque, by increasing the intake charge velocity. The four hole spacers are better than the open spacer for this purpose.

Ditto with Vince.

I`m kind of confused by your post. If you were running a edelbrock carb on a stock intake, then you had to have a adapter to make it work, was it a 4 hole adapter or a open adapter? if it`s a open adapter the best place for it is in the trash, these disrupt the flow as well as the vacuum signal, if it`s a 4 hole adapter, set it aside, as you don`t need it on the Performer intake, if it`s just a plain 4 hole carb spacer, then I would keep it on.

nah it's just a four hole spacer. i just didn't know cuz it was four hole and the intake was open, didn't know if one was better than the other. looks like i should keep it on though!!!
