Hello all; I have decided to post a thread on the conversion of my 70 Challenger RT 440 to EFI six pack. I currently have a normal carb 6 pack on the car but it is time to step it up.
Some of you may recognize that I have another build thread here for my 73 Road Race Cuda which also has a EFI 6 pack on it which I have been working on for about 8 years and recently painted. So, why would I divert my attention (and more importantly my money) to this project when I have a whole other car to put together and get running you might ask... well I guess all I can say is "that is how I roll"...
Actually the reason why is fairly simple for me and may seem odd to others; but the short answer is so that I can and will drive it.
You see, I bought this car in 2000 after a long absence from building cars due to my service with the US Army. I returned from overseas in that year and knew it was my last stint and that I wanted to get back into cars, specifically Mopar. I had grown up with Mopars back in ND throughout the 70's and early 80's and knew I wanted back in. So, I began searching for a BB 4spd Ebody; little was I aware that these had become quite hard to find and expensive (relative to where I left off).
So after some searching I found this 70 Challenger RT 440, AT, AC, PS, PB, 6 way seat, stereo package, light package, pedal dress up, go mango, longitudinal black stripe, black vinyl top, track pack, California emissions car. Most of this was lost on me at the time as I only saw and was concerned with the car itself. At the time, I paid what I thought was crazy money ($5k) for a neglected, abused car without the original engine or trans, however I would come to learn that I got in at a good time and for what I bought it was not all that crazy.
The car as purchased at a date correct 440 and AT (most likely out of a C body) and it appeared that someone was trying to do a quick build/flip and probably intended to try and pass it off as original. Regardless, I went to work fixing all the ugly, rebuilding the engine and in about 3 years had it pretty close to done. I did all of the work myself except the machine work and rebuilding the trans.
At that point I basically stopped as a new career had taken hold and I had purchased my Cuda which I was working on along with many other projects. Last year (2015) I decided to try and get the car somewhat reliable and set about replacing the headers with new a Schumacher Tri-Y set, had Firm Feel rebuild the steering box, added fast ratio arms, cleaned up a lot of missing or incorrect hardware, repainted the engine compartment and trunk, replaced the bumpers with the correct ones, installed a H4/H1 headlight set and built a gauge console to match the factory console motif. And again, the car went back into the shop and sat.
Several weeks ago I was in that shop and looked at the car and decided to fire it up. After having to prime it and play with it, it finally flamed up, so I decided to take it for a drive (mind you, this car has less than 50 miles on it since it was built in 03). Off I went and all the reasons I love E bodies/Mopar can flooding back. I drove it about 5 or 6 miles before returning and at that moment, I decided I was going to put EFI on it.
So, this thread is dedicated to documenting this conversion. I hope some find it useful and/or interesting. If not... oh well. (yes I am still working on the Cuda as well)
Here is the car I started all this with.
