i have a 91 rs was a 3.1 car i am dropping in a non cc carb 305 but the motor i have has a cc hei distributor on it i was hoping to use and was wondering if this will work or if i am going to have any problems with it?

 

Yes, you'll have problems, like no timing advance. If you're going non-computer, you need a vacuum advance distributor.

 

the distributor has a vacum advance and also has the 4 wire plug coming off it that is attatched to the module

 

Well, if it has a vacuum advance diaphragm, then it's not a CC distributor and should work fine. It sounds like it's the older style HEI. While not computer controlled, it is still electronic, which is what the ignition module and wires are for. Instead of using breaker points, the ignition module determines when to fire the coil.

 

so what do i need to do with those 4 wires ?

 

Well, 2 of them will be coil power, one will be the tach wire, I'm not sure what the 4th would be. What colors are the wires? Can you post a pic of the distributor/wires?

 

i will get pictures later but it has a plug that looks almost like a trailer light plug comes off between dist. and cap also has a red wire wich i know is power and a white wire wich i know is the tach wire that come out of the top back side of the cap but this is a totally sepparate plug

 

Hmm, are you sure it's a vacuum advance distributor then? The CC one (non-vacuum) looks like this, and has a 4-pin plug.

 

it looks kinda like that but has a vacum diaphram and the 4 wire plug is about twice that size

 

 

 

looks something like that

 

I searched around google some, since I haven't ever seen a 5-pin non-CC ignition module. The only info I could find says that the extra wire is for a knock sensor, which would retard the timing on knock. Any idea what the distributor came out of?

 

i do not know what it is out of but the vacum diaphram should take care of the timing advance so what would the 4 wires do other than knock sensor wich i am not hooking up

 

With or without the vacuum diaphram the timing will retard with no knock sensor.

 

so what do i do with the four wire plug ? do i need it ?

 

can anyone help

 

The plug for your distributor needs to be adapted to fit you wiring harness for your ecu.

You find the plug on the harness that should go to a distributor, find out which wire is which, 1 would be for knock sensor, 1 or 2 would be for tps signal and Im not sure what the last one would be for.

Once you know which wire is which, cut the old plug off the harness and wire in the new plug. Its kind of hard to help if you dont know where the distributor is from.

Im not very good at wiring and electrical, this is just from my brief knowledge. Someone smart should chime in and help this guy

 

thanks for all the great info i just gave up and bought a different distributor from a friend of mine got a acell super coil

 

there are CC EST HEi dizzies in 1982 trucks they do have vacuum advance

im tired of ppl claiming that no CC HEI had vacuum advance when in fact many were made and i hve one sitting here right now,

form 1982 K10 pickuyp with 305 and EST system and E4ME carb

look it up for yourself

some caprice wagons were EST with vac advance also...

1103465 is the distrib number

they also have weights too

and the 5 pin module for EST system

1103460 is the more common one and yes it has no vac advance,

but just because you havent ever senen a 465 hei doesnt mean they dont exist

whoever started this CC distributorrs never had vac advance crap is a moron.
