Ok ill start from the top and try to include all details so some one hopfely can see what im up aginst.

Ok i resentely got a 305 from a 89 car or so i was told here is what I know for a fact so no one has to go look unless you think what I have found is rong so please bare with me. I look at all GM cars in 89 not one came with a 305 excpt the camaro of corse ever thing els was a 307 so im not for sure if it's a 89 305 or 307. But the carb on it has 2 barrels in the back and a choke in front and then what i think is an injector in from of the choke right in front of that is a vacume line i can get a picture tomrow and will be adding that. as im sure it will help

The back to barrles are covered by anouther set of butter fly's but when i pull the throttle back it dosent open them nor dose it open the choke to feed the first 2 small barrels. Anny info on what this is or how i will get it to work on my car let me know. here is what i have now

a 1992 camaro rs with a 3.1v-6 manual going to a 305 or 307 automatic. If this carburator dose have a fule injectore in it do i need a coumputer or is it just all redy worked in with timing.

Sorry for anny problems reading this im not the greatest speller. If i haf to go throught this to get some one to help me let me know I am decated to learning how this carb works or if it will work if not maby replacment is best. Thank's agin

 

There were no carbs in 89, so it's not a 89 carb.

Does it (the carb) have a large electrical connector with 2 terminals sticking up from the right front corner, on top of it; and another large connector with 3 terminals sticking out the left front corner?

If so, you'll need a computer for it to work properly.

Post a pic of the whole motor, and the carb in particular, maybe we can identify it. It's pretty much for sure from an older car then 89 though, it will be 87 or earlier.

 

"Sounds" like it's a computer controlled q-jet. Carbs don't have injectors...the choke remains close until the engine warms up, the secondary air valve remains shut until the engine can 'suck' it open. With a computer controlled carb, you will need the right computer to run it. If you have emissions, you will probably have to run a tbi or tpi engine. No emissions, run a non-computer controlled carb.

 

one more pic comming just give me a seckond

 

last pic hope this can help iv messed around trying to figure out how it works if i do need a coumputer where can i buy one for this or do i haf to track down the origonal. where i live i dont haf to bother with emmisions. Also there is a wire harnes comming off the enigen it has 28 wires if that help anny. Thanks agin sorry if i dident spell every thing correct.

 

That is defiantly a Rochester Q-Jet Carb. Like was mentioned earlier, I don't think any Camaro's came with a carb in 89. I personally like the Q-Jet. You do need a computer to run it because your distributor is electronically advanced based on a few sensors feeding the computer. Likewise, the computer adjusts the A/F mixture. I currently am using that carb on my 355 I put in my Camaro and it is working perfectly. Good luck..

 

yeap...thats a computer command control quadra jet. As mentioned earlier you need the computer to run it and the appropriate electronic distributor (these distributors do NOT have vacuum advance).

 

That is a 82-85 engine, if that helps any. Multi V-belts, perimeter-bolt valve covers, etc. Looks like it's all there, distributor, etc.

The harness that comes off the top of the motor to teh pass side is the one that goes to the computer.

 

in the final picture, it looks as if the heat stove and foil piping for the THERMAC valve is on the passenger side. on my 84 LG4, this setup was on the drivers side.

now i cant see the whole assembly on drivers side, but the foil pipe is not there, but that may or may not indicate whether or not there is a heat stove on the drivers side exhaust manifold.

RB, although i have never seen one in person, but i was under the impression the dual snorkel air cleaner from the L69s had a THERMAC valve on each snorkel. is this true?

the reason why i bring this up is that it would be interesting to know if he had an LG4 or L69.

 

also there is no mechanical fan on that engine, but again it could have been removed.

i cant tell from the pictures if the intake is cast iron or aluminum, because it appears to be quite dirty.

 

Good point on the V-Belts. I think I might have a computer (no wire harness) from an 84 camaro Berlinetta. It works with that carb and engine. Where are you located?

 

My L69 has Thermac valves in both snorkels, but only has the heat stove pipe on the driver's side.... the one on the pass side just blocks that one off

It would be cool if that is a L69; that would somewhat wake up your car, especially with some gear, so it can rev like those were made to

 

just to make it clear, i was implying that it could have electric fan (which is what the L69s got), because there is no fan mechanical fan on the engine pictured above. LG4s got mechanical fan.

 

for the questions i will get to but first notdaz i live in Tomah Wisconsin it's by lacross. to find it on a map it's where I90-I94 split. the guy i got it from said that if i need anny thing els to call. but im thinking that's why he got rid of it i think the coumputer fried. I would even be willing to make a trip to get the coumputer but i have no licnce right now I will be willing to pay just about anny price for it if it will wrok.


Ok for the questions im not for sure what all that thremal vac and all that is but i know that it gose to the air cleaner there is only one on the passanger side if that's what your talking about. But if your talking about the extra pipe that i was told pushes air into the exaust manifold there is one of those on both sides, but the pump that runs off a belt is seased my teacher told me that i wouldent need it but im sure it adds power or somting outher wise thay wouldent put it on excpt for emmisions.

For the fan i have removed the fan to take the seased pump for the exaust off. so the way i under stand it, it is the not the L69 motor. thanks agin for the help anny info on this with the nifo iv given please let me know. i would like to know for sure what motor this is. and one last question it's not carb related to a extent it is but not relly.

It came with an auto matic transmission the motor only has 66k miles on it i have the 6cylender manual in my car now would it be worth it to buy clutch and all or just keep it auto because it's coumputer controlled i thought it might mess up the carb.

Thanks agin sorry if i miss spelt anny thing im getting better. notdaz agin i would like to get that coumputer from you if the guy dosent have the coumputer for it even if you haf to ship it ill send you a check or somting.

Thanks agin.

 

if you have the 6 cyl manual you cannot use it on the V-8 motor like it is, either find a V-8 bellhousing and reuse the manual tranny or use the auto that cam with the motor (if you think it's in good shape), the auto tranny is probably a 700R4 which will have the lockup torque converter in that case you will definatly need the computer.

either way you are looking at a pretty big job, swapping from a V-6 manual to a V-8 auto is a pretty daunting task for even for those of us who have done it a couple of times. no offense but you don't seem to have the knowledge base to complete this without a huge amount of frustration on your part. BUT, if your willing to attempt it we will be here to help the best we can.

 

you have a good point but anny thing i start i never quite iv payed 300$ for the motor and my V-6 is blowen or well locked up so that's out of the question. My last resort is changing it and i plan on being a automecanic in real life ill be going to wyotech or UTI and im trying to pull in all the info i can so i think this will be a good learning experince thanks agin ann more info would be nice

 

Know its old post but is there anyway to covert that CC Qjet to NON CC and adjust the airfuel? I have one i want to use but...

 

i have investigated this for a couple of weeks before i baught a new carburator it is possible to use it with out the coumputer but the problem in it is there is no way to adjust the jets best bet is get a new carb i picked up a 750 square bore holly carb for 75$ and it's plenty of air and fule mixture if not over kill

 

yes but i dont have a square bore manifold on there, im using 89 heads with an 86 Qjet manifold (slotted bolt holes yesterday) and the Qjet is freaking running rich as it possibly can.

Im going to get a spreadbore to squarebore adaptor and throw a holley 650VS on there tommarow because i cant think of an easy way to convert this Qjet over to non-cc. thanks for the confirmation, though.

 

You can't "convert" a computer controlled q-jet to non-computer control. You can convert a computer controlled engine to non-computer with an older non-CC q-jet carb (or a new Edelbrock Performer q-jet) and a vacuum-mechanical advance distributor.
