I finally decided to upgrade my CIS to EFI. After adding a supercharger and using a DWUR (ultimately replaced by my Arduino controlled design) I found that the limitations of the hardware did not allow me to exploit the engines capabilities and it was time to move on.
Here is a post on that build:

I want to thank Chris at Turbokraft and Andrew at Rasant for talking to me and giving me enough info so as to select the components I did.
Timeline: I am trying to complete this in two months. My daughter is out for the summer on an internship so I am using her car and hope to have mine finished by the time she gets back.
EFI:
For the conversion I decided on using the AEM infinity system. I wanted to get as much of the items needed as possible from the same source so I went with Rasant Products.
Manifold:
I decided not to source a 3.2 manifold but to use the SC manifold with the injector adapters made by Rasant. Since my system is supercharged, I have a nice aluminum air box that I will reuse. I won't cut it, but will leave it as is. The 79 cars have the large port intake manifold so I'm set with that.
Ignition:
Since I already had a timing wheel on the crank pulley from an electromotive ignition system, I decided to get the Clewett Engineering cam sensor and go full sequential with the Rasant COP system.
Wiring:
Since the AEM has many inputs and outputs that can be used for additional sensors, I had a custom wiring harness made by Rasant so that I can get CAN signal, put other inputs and activate other outputs (always need to have future projects!)
Fueling:
For fueling I went with injector dynamics ID720 injectors- should provide sufficient fuel for the foreseeable future!
Sensors:
Already had a two-bar MAP sensor, so I'm adding to that an IAT, TPS, fuel pressure sensor and two knock sensors. I purchased the Porsche knock sensor bridge and will see how can I install it with the engine in the car.
Possible issues:
1) I recently was able to make my AC work and the compressor may interfere with the fuel rail.
2) On the other side of the engine the air return on the bypass valve may interfere with the fuel rail.
3) No load-bearing dyno that I know of (so far) in S Florida. This will make tuning harder though not impossible.
Pics to follow.
