Hello again. I am looking to do a little project and would love some help. After changing my cam (nothing to crazy), lifters, pushrods, water pump, fuel pump, gaskets, belts, and hoses, I find the carb is all thats left. I am not really great with the technology of the CCC E4ME on my car, and no one locally will touch the thing. I want some advice about swapping the carb, distributer, removing the emmissions, installing headers, and what to do with the computer, hoping that this is the better route to go.

My first thoughts were to remove and save, all the emmisions control parts. I was looking to replace the carb with an Edelbrock Performer 750, and the distributer with a MSD HEI Vac. Advance unit from a local vendor. I am under the impression that the original intake is not a bad one as long as I seal up the EGR port well. For headers, a nice set of shortie Hookers will do Fine. The big question is what to do with the computer. Some tell me as long as the new distributer has power to computer and tach, the torque conv. will lock up fine, others say I am opening up a can of worms. A SUmmit tech told me all I would require is a JET stage 1 chip which will prevent the computer from "hunting" for air/fuel data.

If anyone has some advice, I would be greatly appreciative, as this will help me to complete my first restoration.

 

Do you think the carb is holding you back now? Unless you are taking it to redline, your carb just may need some jetting I would think. Odds are under 5000rpm the existing carb may be fine.

850 horse Nascar engines use an 830 cfm carb.
I had a built 440 that made 500+ hp, and it only needed a 750 Holley DP. It just needed
to be jetted properly.

Search on Google selecting the right size carb.

 

It sounds like you have your head around most of it. The carb, computer and dizzy work together and without any 1 of the 3 the other 2 cannot work.(actually they will work but not well) its a simple as unplugging the connections from the computer behind your seat and installing your choice of carb and dizzy .i like your choice of msd .if you want you can go the extra step of removing the 2 wiring harnesses as they all come out together in one big bundle. Your transmission will still drive fine and there is an easy modification you can do to the TH350c to make use of the loc up without the computer....thats just a simple search on here.

 

thanks for the advice. I am going to look at the harnesses tonight and really look at where they are routed. Do you have any idea what happens to most of the sensors that supply data to the factory gauges? Are they directly run or do they get info from the computer?

 

If you remove the CCC stuff no sensors are needed are there are not many anyway. Long tube headers are an easy install too. Doing exactly what you asked has made a world of difference in mine.

 

your gauges will all work fine, they are not connected to the computer. temp, oil pressure, engine check, speedo ...the lot . Your harness travels down your centre consol under the shifter plate then comes out in 2 feeds through the firewall around the brake booster area from memory. It comes out in one big slug with all the sensors still attatched to the ends. You need to pull it backwards into the cabin to remove it.

dont worry about the arrow thats from another post but you see that big hunk of crap on my floor ..thats it and you can still see the thermostat sensors and carb connectors on the end.
