How do u tell a Non cc dist from a cc dist?? im all new at the eletrical stuff...i have a non cc qjet with a elderbrock intake and idont no if i have a cc dist or a non cc one...it has a vacuum advance on it and 3 plugs in the opposite side..also wut is HEI

 

HEI is GM's name for their electronic ignition that replaced the old points distributors sometime around 1975.

A non-CCC distributor has a metal vacuum advance can sticking out the side of it. Underneath the cap it also has a weight and spring centrifugal advance mechanism and a 4 pin ignition module.

 

i think mine is a HEI it has the metal bowl vacuum advanced but i never changed the dist when i changed the carb and intake

 

If it was made after 1974, it's an HEI. That doesn't mean anything.

If your distributor was original, it wouldn't have a vacuum advance can.

 

Heres a pic of it..so this will work with my non cc carb...what vacuum advance hole should i plug it in

 

That's a non-CCC distributor as evidenced by the silver vacuum advance can. Plug it into a source of ported or non-ported vacuum, depending on what you and your engine prefer.

 

do u no what port is the best i have it in the only port on the back

 

Usually with a stockish cam it'd be connected to a ported vacuum source on the front of the carb. A ported vacuum source will have no vacuum at idle, but will see vacuum as soon as the throttle blades are opened.

 

thanks for your help
