Carb Spacer

Monte Howard · 07-29-2013, 09:14 PM

Who makes a good 1" - 2" carb open plenum spacer? I am working on friends bracket car, don't know a lot about the motor. He bought this back halved s-10 and motor as a package. I do know its a 377 sbc .570 ish flat tappet cam. 270-280 @.50, aluminum heads that have no name on them. Nice open plenum Edelbrock intake, Holley 4150.
Not looking for any top secrets. Just want to buy a good carb spacer that works.
Thanks Monte.

Hvh makes a nice 4 hole I use a lot on dirt modified engines seems to average anywhere from 6-9 hp on the Dyno

Comp Cams makes a really nice one with vibration dampener built in. Great part, makes power, not cheap!

X2 on the HVH spacer - they make a killer piece, 4 hole transitioning into an open, my own preference is the 2" one, we have seen 31hp on the dyno on one occasion with only the addition of the 2" spacer - might have been a bit too small of a plenum added to the change, but 31 is still 31.

Spacers are a trial and era part,I 've seen cases where they make 25,loses 25 ,or does nothing,it just depends on combo and how close plenum size is to what engine wants.
