Does anyone know what all the vacumn take offs on the Quadrajet are for ?

There is a large one from the base plate with a threaded connector, and many small , <5mm dia. ones.

Many thanks

Norm - not familiar with this carb, but I should think the large one is for brake servo (should be "untimed"), the smaller ones will be a mixture of timed or untimed. No huge deal - just cap 'em off with rubber thingys and swap if you need to. Are you using a vac advance distributor anyway?? Hopefully there will be a middle sized one (untimed) for the PCV.

Hi wilf,

The Advance etc.. is already piped luckily!, I'm using HEI to keep things easy.

I'll bung em all up and see what happens......should be starting it in a couple of weeks......BBrrrrrrmmmmm (hopefully!) }>

Many thanks
