Just picked up this car over the weekend with 60k on it. The previous owner used it for drag racing. He had a different engine and tranny in it at the time. He put it back to stock except for one thing, the carb. It has a edlebrock on it and I would like to go back to a q jet. The more I research the more confused I get. I know it is computer controlled but not sure on the choke. Is it electronic or hot air? I contacted jegs and they say it is a climatic choke. Thanks

Electrically-heated choke. Hot air stuff was mostly back in the 70s.

Jegs has one of those, did he just give th wrong info? Or is one better than the other?

All computer-controlled (stock) carbs are electric choke.

So, ultimately, it doesn't matter which is "better"...

This is the carb you want.

Ending in "205". Thanks, I spent hours last night trying to find that. I remember one post that had the carb number

PN 17083207 was also used, according to GM info.

I think it was first in this one.

Yup, you referenced my Tech & Resto post on another site. I initially created this on NECF and utilized GM Dealer Service Parts books for all of the info.

Here is my original NECF thread on the E4ME Qjet

those q-jets are great carbs IMO, i would honestly call jegs and get a jet stage 2 q-jet if it were me, i had a 84 L69 back in high scholl and loved playing with that car, she responded very well to carb mods, the best one i recall was loosing the secondary spring on the back pass side of the carb to get them to snap open faster. if my current 84 came with the L69 i wouldnt be going lsx, just really enjoyed my experience with that engine!

Agreed... the Qjet was the best "real street" carb ever created. The E4ME was just the logical evolution and gets waaaayy better mileage than the TBI system that replaced it, provided you arent heavy into the secondaries all the time.

Just so you know, you need a computer type distributor to run the E4ME as well. If the car has an Edelbrock carb on it right now, most likely it has a non-computer mechanical/vacuum advance distributor on it as well.

Hopefully the computer, harness, and sensors are all there. If not, you're better off getting a non-computer q-jet to put on it (assuming you don't want to run the Edelbrock).

By the way, what intake manifold is on it? An Edelbrock won't bolt (directly) to a stock intake, and a q-jet won't bolt (directly) to a square-bore pattern aftermarket intake. Some aftermarket intakes can accept either a square-bore or spread-bore carb.

Not sure, just bought the car and basically drove it around 100 miles and then into storage. The dual snorkel seems to sit a little high, adapter plate from spread to square bore? I just purchased a lt1 and t56 that I want to install. That is a little ways out. I want to return to the stock drivetrain and color in the mean time.

Got any other pics of the color combo - looks custom.

Throw the carb away and get ya a older model year non emission Q-jet.
Simple install.................

Looked at the car today and it has the adapter plate. The manifold number it correct to the car. Distributor looks stock, back at it tomorrow.
