    Is there a purpose for it? Does the carb perform better? I'm gonna run a new Q-jet and was wondering what the deal was with carb spacers. /forums/images/graemlins/confused.gif

    Don't need it, I saw you on the freeway, you don't hot rod your truck, and doubt you will be crawling up hills at higher rpm /forums/images/graemlins/waytogo.gif

    Don't know why but everyone runs them. They are around $25 in the bling section of AutoZone and PepBoys near the carbs and intake manifolds.

    Are you saying he drives slow? haha.

    A 4-hole carb spacer isn't going to hurt performance any on the bottom end but will get you about 5hp and 5ftlbs above ~4000rpm. Sometimes people use them for the sole purpose of getting rid of heat soak. The 2 hole or open spacers are only used to increase plenum volume and will hurt low-end performance. Also defeating the purpose of a dual-plane intake.

    I had to put one on the 400 small block in my plow truck to allow the carter afb to fit on the stock quadrajet manifold.
    I had a few hanging around, one was open center with a thin slice of the aluminum left in the center of the hole(like a divided plenum on the intake),the other was the 4 hole style--tried them both,and contrary to what they say about the 4 hole one being better for low end tourque,it dont apply to my 400--I put the open hole divided one back on after trying the other one,between that spacer and putting an open element air cleaner on it feels like 50 more horses easy--in the winter when I have to run a closed air cleaner with the hot air pipe to prevent carb iceing,and I lock in my fan clutch so it wont boilover with the plow on it,it feels more anemic than the 250-6 in my other truck--its amazing how much it cuts the performance and mileage! /forums/images/graemlins/eek.gif
    Some of the power gain may be due to the carb itself,I suspect--and those spacers suck in the winter,the carb never gets hot enough to keep it from iceing up when its really cold out,makes it run rich and stall a lot--I have to use isopropanol dry gas to keep it running decent enough to make it roadworthy---great in the hot weather though. /forums/images/graemlins/crazy.gif

    Check out this article at HotRod.com on carb spacers.

    Haven't read the whole thing myself yet, but I think it might help you out.
