i have an 84 camaro 305 engine. we replaced the computer controlled quadrajet carb with a non computer controlled quadrajet. when i mash the pedal the car itself wants to die out. am i getting to much gas? or is it something else? it has stock hei not sure if need a vaccum advanced one or not. its an 800cfm carb we put on. any help is appreciated. bill

 

You need a distributor with centrifugal and vacuum advance.

 

Do.

As in vacuum/mechanical advance.

 

so that will cure my problem then? whats centrifugal and vaccum advance? where can i get one at?

 

It might not entirely cure the problem, but it's sufficiently wrong that there's no point trying to do anything with the car until its fixed.

In the factory setup, the ECM varies the timing for different operating conditions based on the information from various sensors. You've eliminated the sensors on the carb, so the ECM can't control the timing anymore.

A distributor from an older non-computer controlled vehicle would be a start, or there are numerous aftermarket ones available.

 

so by putting a new distributor w vaccum advance that would controll my timing? i dont understand the whole carb and dist. thing

 

Yes, the non-computer controlled distributor has a weight and spring mechanism to advance the timing as engine speed increases ("mechanical" or "centrifugal" advance), and a vacuum pot to advance the timing as engine load decreases ("vacuum" advance).

 

thanks for clearing that up.. by chance no any places that sell em cheap? summit has sum but dont know which to get

 

ok i found a dist cheapest is 240! can u make a stock hei distributor vaccum advanced? like i took computer off carb, would that dist running the sensors on carb be able to be made to work?
