Just wondering what all is involved in this. I am fed up with the wiring issues and I want to clean up my engine bay. I have a Torquer 2 intake and a holley 600 CFM carb.That I am planning on using. As for distributor I was goona get one from Summit. So what all would I need to keep in terms of wiring harness. I want to retain the electric fans. And get rid of the rest of the computerized garbage. Any help provided is greatly appreciated.

Swap is pretty straightforward. Pull TPI manifold, install carb manifold, install suitable carb, configure fuel delivery (Diaphragm-style bypass regulator/stock pump, mechanical pump if your cam has provisions for it, inline pump and regulator,etc...lots of options).
Past that it's just a question of what wiring you want/need to keep and, like Five7 stated, emissions regs in your part of town.
exactly the emissions in some states won't allow you to pass inspection. Also keep in mind to if you want complete mechanical i would suggest going to a vaccum distributor. My setup is 600cfm edlebrock with accel distrbutor vacuum. performer intake manifold. And if you want to go further into it like i did. Change out the electric choke on the carb to mechanical then less electronics and wiring to deal with.
Emissions are not a problem. The car is registered in Tennessee. And yes all 1st gen chevy small blocks have the fuel pump or a removable blank off plate on the block. And is there anything that I need to rewire once I remove the computer??? Right now that is my biggest concern. If once I yank the comp if the gauges and all that stuff will still work. Thanks for the info so far.
Alright So I have decided my set up ........ Wienad warrior intake Holley 650 4 bbl,with an accel vaccum advance distributor. Now Can I just get rid of the ECM completely or will it still be needed for certain things ???
my oil,water gauge did not work once i removed the ecm and the wiring, so i installed mechanical guages and senders for the engine. your trans lockup in overdrive won't work. so far i drive the camaro without a lock up kit and it runs fine.
Thats weird that your gauges didnt' work. Since they are on a different circuit than the ecm. but i did the same i removed my electronic sensors and went mechanical.
Accel distributor is the same one i have it is by far a good one.

I knew about tcc lockup, i was told that it will burn out the tranny if u dont put one in. I was also told that the gauges work w/o the ecm.
I am replacing all my gauges with digital gauges. Ive already fiberglassed the old molding around where my gauges were and Im going to drill out holes and put them in there. One of the owners of one of the speed shops down here said that they plug right into the wiring for the old one and that it will work without the ecm in there

I would be interested in your tpi intake if you are willing to get rid of it after you swap it.
white wolf, if you are interested, i have the entire tpi system, incliding new accel 24 lb injectors, new ecm with a prom, distributer, coils, sensors, that came off my running 89 iroc 5.7 camaro. i converted to carb.

Does this include the wiring harness? If so can you give me some pointers on how to take it out and what I still need to keep??
it includes everthing i said plus the mass air flow sensor and rubber intake boot. i have the wiring but it needs repair. you are better off buying a new painless wiring kit for about $400.00. i'm asking $300.00 plus $55.00 shipping
I am switching to carburated. I am just wondering if you could help me with givin me some info on how to take my wiring harness out. I really dont want to pay someone to do this.
When I sold my tpi setup with harness. Drew the guy on here thats his id. I kinda seen what he was doing seemed alot of work but he did the whole tpi setup with ecm and harness in around 2hrs. Fast it would of tooken me 6hrs LOL. but you take the harness off the fuse block, unbolt one bolt behind the transmission which has one bolt holding the harness on. Hmm trying to remember. Oh then you kinda slowly pick up the harness and see where else it connects on the tpi and remove it. and on the passenger side fender *easy if the door opens to get to it* has another block thats on the inside of the door. and you remove that. I believe its bolted on inside the car where the ecm is connected. Just some pointers. Not at all expert on TPI as had left my harness in my car and he gave me some pointers on how to clean up my wires. Which i will do when its little more warmer and when i have my conversion from auto to manual done first. Want the car going again :P. but thats all i can really help just feel and unbolt. and it will come out easy after everything unplugged and unbolted.
There is a difference between some Camaro's and Trans Am's in the mid years. Trans Am's have the electric speedo and the Camaro's have the cable driven speedo. My 86 T/A had the electric speedo and the two wires, purple and yellow, were in the ECM harness to pass through the passenger side kick panel. I cut the two wires out and connectged them back together but the speedo didn't work. Turns out that the speedo module, mounted on the ECM carrier, gets the ground from the ECM harness and not the dash harness. You will need an additional wire to splice into the black w/white stripe to ground the speedo module and then it will work. Other than that I had no problems going from an ECM carb to non-ECM carb.

Now that I am looking at all that I can possibly mess up by this I may just take it to speedtweakerz. Its the shop down here. One of the owners swaped to carburated on his old 3rd gen and I thnk I will have him just take out all the wiring and put in my gauges after I get the car runnin again. I really have a tight budget so I may try to see what I can get off myself with out messin it up.
