people take off the ccc for a cleaner engine compartment and few other reasons. I like to say my car has a holley and a mild 350 under the hood,...not a 305 wit a million hoses and wires that i have no idea what they do. Plus i appreciate my car more with all the upgrades and changes


85SS 350v8, 200-4r, bodywork and H4 upgrade coming soon

I have an 85 with a 350 swap from a truck with the qjet on it. Im buying an edelbrock performer 600cfm carb matched with the rpm air gap manifold. Obviously (since its a monte) i want to bring it to car shows and have the engine compartment looking good. The wiring harness for the qjet looks terrible so i would like to take it out and put the non cc carb on. I have a hei distrubutor and a 200 r4 transmission. What else do i need to get to have the car run good? can someone give me a list of everything else i would need for the car to run/shift normally? Thanks

I have a 84 Monte Carlo SS with a 355 and 350 trans. The question has been asked before but not really answered. Do you need a lockup kit for a 350 trans? Not trying to bring up old stuff but need new here and need some info. Thanks.

It depends if you have a 350 or a 350c, the 350c will have a electrical connector on it.

What if you dont run in overdrive? I was told if you dont drive on the highway much, and not driving in overdrive (regular drive) you wouldnt need a lockup kit for the trans, I have a 200R4, and removing the engine harness, but really dont wanna remove the transmission harness, due to having to buy a lockup kit. I'd really like some info on that. I basicly read every post here, and still didnt get a good answer. I've heard of people driving other cars ('80s Caprice), removed the engine harness, but kept the computer and trnasmission hooked up, and drove in overdrive for along time, I dont believe he ever had a problem with his trans.

The transmission harness is a part of the computer harness. GM made non overdrive transmissions that were still lockup.

When you unplugged the connector under the passenger side dash you unplugged the power feed to the pump. It is the tan wire with the white stripe in cavity B of the 8 cavity connector. The ECM harness has the fuel pump relay on it so you will need to connect the circuit. Do this by taking power from the back of the alternator through an immediate 20 amp fuse. Then run the wire from the fuse to the oil pressure switch. Then run a wire from the oil pressure switch to the tan wire inside the car. The fuse will protect the wire in case of a short and the oil pressure switch will turn the pump on when there is oil pressure. Since you have fuel in the float bowl the engine will start on no pump and then the pump will run until the engine is stopped or loses oil pressure.

If you got the harness out without cutting, it is in good shape and you want to sell it shoot me a PM. I have been looking for one.

i had it out and realized it killed the power to the pump so i plugged it back in the harness and connected it back to the oil pressure switch and the fuel pump relay i couldnt figure out what to do. i would sell it but the guy who put in the motor didnt know what to do with it and cut some sensor connector off otherwise it would be in pretty good shape.... so your basically saying i need to splice an inline fuse from the alternator to the oil pressure switch to the tan wire in cavity b of the 8 cavity connector?

Hmm ok I did this and when I hooked it up to the alternator it kept the fuel pump on then when I went to start it just poped the fuse. On the oil pressure switch it has two prongs I ran one from the in line fuse to the alternator and the other to ground? The in line fuse was also tied in with cavity b on the connector idk I guess I'm confused on this and overlooking something

Wire From Alternator to fuse. Wire from other side of Fuse to one side of the Oil Pressure Switch. Wire from other side of Oil Pressure Switch to Cavity B of Connector. Other side of Cavity B should be a brown wire.
FP should run when Oil Pressure is available to close the Oil Pressure switch. We're assuming you have enough Fuel in the bowl to start the vehicle and obtain some oil pressure, which will then start the pump and keep it going.

Hey guys-

We have a 350 crate engine - going with no computer, non-ccc quadrajet, new msd dist. It has been 2 years since we started the frame off, so it is not just as easy as removing the CCC wiring harness.

Here are a few clarifying questions on wiring if you can help:

1. Since the oil switch on the back of the intake controls the signal to the electric choke, I imagine that I need that sensor in place, correct?

2. From the engine harness it seems like there is a loom from the front passenger side of the engine that goes out to the passenger fender. I think it is to the old barometric pressure unit. I can cut those wires, right?

3. At that same place there is a two prong coupling that used to go into the CC harness. pink and black wire and a black wire. I can cut those wires, right?

4. The brown tach wire hooks into a white wire in the loom. I think that the white tach wire and a red power wire show up in the connector that used to go to the old coil. I simply hook the tach into the loom the same way and take the old coil connection and manufacture the two leads to the MSD, right?

Thanks in advance,

Larry

I have a 1986 Monte SS. I have replaced the 305 with a Jasper 350 ci 300 hp with 366 ft pounds of torque. 700 r4 transmission, headers, hi-flow cat and a alburn posi unit. I've gone through 4/QJets. These carve keep going bad. I want to disconnect from the computer but I don't know what would be a good fit for this engine. Can you help please!
