Well, I did it. I fuel injected my Cuda. Not using an expensive aftermarket EFI set up. I did it mainly using junkyard parts. Inexpensive EFI is possible for small-block mopars.
I was always a Mopar-guy, but I did spend about 5 years pushing the limits of Ford’s EFI system in the late model 5.0 Mustangs. I had a 550 horse-power, daily driven Mustang using the factory Ford EFI system. I did a lot of things that pushed the limits of the stock computer system, and I was amazed at how versatile and adaptive their mass-air system performed. The Mustang’s EFI system can adapt and adjust to perform optimally under a vast range of variables like cam changes, head changes, cubic inch changes and supercharging. I figured that their system could be adapted to my Cuda's 360 for much less than buying an aftermarket EFI system. Obviously, I had to do some fabrications and modifications to get the system to work on a Mopar engine, but I did it with the help of some really cool Ford engineers.
By the way, ALL aftermarket EFI systems are some version of speed density which requires you to tune or manually program the fuel tables for the engine to operate. This might require an expensive wide band O2 sensor or some dyno time to get the programming optimal. Any significant change to the engine like a cam change would require re-programming. The Ford system uses a mass air sensor and essentially tunes itself to run optimally.
I am impressed with the results of the conversion and how nicely a sequential fuel injection system performs on my Cuda's 360. I am still testing and experimenting with my Cuda, and I will post performance and mileage results later.
Below is the before and after picture of the engine.
