It's ironic that I found this thread because I've settled on this system for my '65 Dart/'69 340, too. I like carburetors but I'm done fooling around with them, especially if I want to take my car up to higher elevations.
I put information here not to try and warn anybody off of going with this or any other system. I just want people to know that it's not all as simple as bolting one on and off you go. You still might have issues to solve that challenge your sanity. You should also know that your not done futzing with the system after you finish the install and close the hood. There is still a lot of programing to do even with the self learn. Fortunately there is a ton of videos and support is sort of available. On the positive side. I have timing controls like no other and cold start problems don't exist. Unlike a carburetor I can also be very aware of running overly lean or excessively rich at "any point" in the rpm range. You can say a carburetor can do that and I believe you. Honestly I do, but that covers, I'll go high and say about 5% of the carb population are of guru enough status to even pull off or actually even take the time to pull off an exceptional tune on a carb. Some have a friend that they trust, some go to professionals and some throw parts at it. Which is a note here of my failure. I threw parts at this that didn't solve the problem. About an additional $400 not counting my time. My problems finally went away with replacing the bad new fuel pump. Last note: If you buy the H/S system you don't get the cable that lets you run straight from your computer. You have to transfer data (via a macro card) from the hand held to a computer and back again. You can get away with just the hand held if you like. Good luck and let us know how it goes.
