i have a 86 T/A with a computer controlled 305. i am disconecting the computer and all i need for visual inspection is the air tubes and pump and catilitic converter so im discontecting the computer and ripping most of the crap off. i know that i have to get a new distributor but im not sure what to do with all the tubes and junk and is there anything else i need to do any help would be appriciated. by the way it has a carborator.

 

yes. send the wiring for the sensors and the computer to me I'll put them to good use

 

How are you planning to control the MC solenoid on the carb without an ECM? What about the cooling fan? Torque converter lockup? EVAP canister purge? (I'll bet that you'll need a canister for a visual.)

 

my uncle is a mechanic and he does emissions and safety. and he told me the only thing he has to look for, here(utah), in vissual is the A.I.R equipment and catilitic converter. im getting a new carb. im planning on doing switches for the converter lock up and the cooling fan does any one know how to do this.

 

Could use a redundant fan switch (grounds when coolant temp reaches the switch's temperature) hooked in line with a relay. Wire the sensor in-line with the relay so it's powered up by your ignition key; then wire the fan thru the relay so it's powered directly by the battery.

 

Basically everything coming from you passenger side harness is puter related, the driverside is your vitals, such as ignition and gauges.

Take your time and follow them around, it's pretty simple.

 

no offense, but i dont really see why you're ditching the comp. as for ditching the carb for a non-computer controlled one, what do you plan to do?

Theres nothing you can't do with your current carb that you can do with a non electronic model. The only things that are on there are a tps and a mc solenoid, both of which are good things to have, other than that it's just a normal carb you can do plenty of modifications to if you felt like. The computer will work just fine unless you're planning on doing some 9 second drag runs.

It just seems to me you'd just be doing alot of work and getting almost no payback in return, despite what neophytes say, the cc carb/ lockup trans setup is pretty simple and responds just the same to any old hotrodding tricks.

I've gotten cars that were "converted" to fully mechanical from cc carb. I can't say they ran any better, in fact most ran significantly worse because the person who ripped out all the electronics didnt have any idea what he was doing besides "damn electronics costing me power". You can expect your gas milage to drop by about 5 mpg too.

So just take it easy i say, study up on your computer controlled system, It's actually a pretty nice system, i'd take one over a non-computerized one anyday. I have a 84 buick with a cc quadrajet i use as a daily driver. I even switched the original 307 out for a 350 olds with no modification to the carb except some richer jets.

check that link out, gots some good info on working over cc carbs.

 

yes this is true but im sick of all the hoses ,and yes i know you can get rid of most without touching the computer, but the engine bay looks cleaner and its eaiser to work on. my carb also hesitates when i step on it. and im not seeing why i would lose gas milage if i use a torque converter lock up switch.
