I don't understand this at all. How does drive by wire work? What is the change over process for my 5.7 into a 71 challenger. What all do I need, can I get every thing from a doner car, or a junk yard?

I still don't understand, can I just get the gas pedal from a vehicle that matches my motor and mount it to the floor boards of my car, then plug in the harnes, and away I go. I have the engine, computer, and harness, am I just lacking the right pedal?

That is how this engine is designed to be operated, [electronicaly] I'm not sure if normal cabel operation is even a realistic option. Like I said, I don't know any thing about drive by wire, that is why I'm asking.

Dude do yourself a big fat favor and use an old school cable. Thses cars are DOGS because of the "drive by wire" Maybe if it was a 4 speed...
Problem is, if he doesn't want to do drive by wire, he won't be using the stock ecu. Can the stock ecu be recalibrated for a cable op? I thought there was some way of getting a cable op calibration without going to an aftermarket efi controller.

There is no way that I will ever concider putting a carb on it. Lag or not, the efi stayes. If there is a simple solution to using the cable, insted of the drive by wire, then ok. My goal is a very driveable, dependable car that I can do a 5,000 mile vacation with, if and when I want to. It will never be on the track, but I definately will on it from time to time. I do appreciate all the different views and opinions. If there is an realistic, inexpensive option to run my original set up, that would great, especiallly if it gives quicker response. Thanks every one.

There are several cable throttle bodies that will bolt right on, MP has a direct fit part and there is an FAST adapter usually seen on ebay that allows an ls1 TB to bolt on.
The issue then becomes 'which pcm do I use?', because drive by wire was the only thing used in production....if you want to use a stock computer, you're also stuck with drive by wire.
So, converting to a cable operated throttle body means also converting to an aftermarket pcm. There are plenty of them out there to choose from that will all work fine, but not all of them have an off the shelf harness. If you want to modify the engine and need tuning capability, consider that approach. Usually after a guy has sent his stock computer out a few times at $400 bucks a pop, this option starts to look good.
Staying with the drive by wire and production style pcm creates another potential issue not brought up yet....what trans are you going to use? If the trans requires throttle pressure/kickdown input from the throttle, then check out the Bouchillon setup/'03 DR based pedal assembly (it isn't on their website, call them up).
'03 DR pedal assembly uses a short cable connected to a black box which then sends signal to the TB. All other years and models don't have the cable or other moving parts, and could be used with mtx or applications that don't need throttle pressure/KD linkage....the extra moving parts of the '03 truck setup makes for a handy place to set up a kickdown cable for the trans.
I'm not a naysayer and I like FI, you can do this any number of ways depending on what makes sense to you... But I have to say I'm also partial to a carb setup because it reduces the cost and complexity so much. You get a carb which you probably already have, an intake, msd box, msd harness, and you're done...it runs, and you can set the timing and fuel anywhere you want whenever you want instead of sending the OE computer out and hoping they get it right which does not happen every time.

They make carb'd intakes for new Hemi's so I don't see why not.
You don't see why you can't simply remove a stepper motor from the system because you don't know, or want to know, how EFI and ECUs work. Your answer to everything is a carburetor, and that's not what the OP is trying to do here.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
Send a PM.
