Q-Jet

[MrSony]

I meant exhaust noise. That wouldn't be bad either.



This is supposed to be a "Performance" chip. But I cant find any literature in this.



My parents put some alpine speakers and cd player in it. 16 years ago. I may look to put something newer in.

I couldn't find anything either. I'd ditch the CC all together, but keep it in a box and just go with a normal jet and HEI. Clears up the engine bay and makes tuning way more effective.
And since there's already a new radio, skys the limit. Unless you don't want to cut up the dash which I suspect you don't by the sounds of it.

This car was handed down to me from my mom. And I can tell she is still attached to it. She and this car have a slight history. Short story is it is the first car she has ever bought for herself. Which explains why everytime I go home she has done all the work for the parts I have picked up. Which was a new cat and a new donut. So changing whats in there already is no issue but doing bigger I want to rule out for now. And what is the HEI an abbreviation for, I have an Idea headers, exhaust, intake but Im not to sure.

Ha well I guess that could work, but it means HighEnergyIgnition. It's the style of distributor GM switch to halfway through '74 that has the coil in the cap. Your cutlass has that but a computer controlled version. If you so wanted to ditch the computer (but again keep it in a box in your closet or a safe moisture free place) the distributor would not advance timing so you'd need a non HEI distributor. Really any Olds 350 HEI from 75-1980 would work. They fit the 307 like a glove and have somewhat better timing preset into them with weights and springs. Basically ditch the ECM, headers, intake, and non cc qjet and distributor, tuck them away incase you want to sell the car, and you'd already have a nice peppy car that is actually adjustable and tunable. The computer basically negates anything you do because it treats it as an abnormality or as if something is broken.

Also if it's allowable in your area ditch the EGR, or make sure everything is working properly. You'd have to get an intake with EGR provisions if you keep it. Something akin to this: http://www.summitracing.com/parts/edl-3711/overview/make/oldsmobile This'd look beautiful on a GM blue engine or Olds Rocket 350 Gold. I know it's not a factory color for that year, but they look cool gold man.

Ditching the ccc for anything under 500 hp is just a waste of money. First you need to find a non ccc Olds Qjet and have it rebuilt to 307 specs, then tune it. Then you need a non ccc distributor and tune the mechanical and vacuum advance. Then you need to figure out a way to control transmission lockup as the ECM handles that. Also I believe in the Cutlass, the ccc also runs the a/c, so you have to figure a work around for that. When all is said and done, you will have spent a few hundred for zero power gain, reduced gas mileage, reduced engine life, and higher pollution output. They sell o2 sensor bungs you can install on any header, there are weld on bungs, clamp on bungs, and bolt on reducers with sensor bungs. Several people have successfully run ccc on big blocks. Performance chips tend to mainly have more aggressive spark advance timing curves, I never heard of a performance chip for olds before, there are a couple for Chevy such as L69 and ZZ4 chips.

This would require heads as well correct? I have 7A and not 5A.

Aside from the one that I have already. There is one from Hypertech thermomaster that is said to work for the 307. And there is someone who said to use one on another site. Ill find it and quote it in. All my searching came before joining this Forum. which I am glad I did. I went from having a motor with little options to being able to see that there are more. Also snapped some pics of it. Putting them in my new Forums post.

Yes that would requre different heads. But they would be a GREAT improvement over those crap 7A heads. Good for MPG, but that's about it. I'm not sure if they'd need to be modified to use with the roller cam you should have with 7A heads, but they shouldn't be. Mids 70s Olds heads (or '70-'72 if you can find them. Get hardened exhaust seats and a valve job, few hundred dollars max), that intake I linked, headers and dual exhaust and if you're feeling gutsy a new roller cam with higher lift. Or you might have to go with a flat tappet cam with the older heads.

Not bashing you, but, since you did not know what HEI stood for, I think you should leave well enough alone. A lot of otherwise good mechanics I know could not remove the CCC system and re-tune better. As far as I can see, that chip is a stock one for your car, and no longer available. Read: http://tech.oldsgmail.com/ecm.php Plus, keep in mind that on the E-jet models, the computer only manages the primary side. You are free to play around all you want with the secondaries. But being only a 307, I'm thinking you are better off not fooling with it.

No offense taken. We all start somewhere. And youre right it don't believe it is a route I want to go. And awesome that it is the stock one for the car. Even batter that it is unavailable now. Is there a way to clone it for others, in the event they want it?
