If you take some time to learn the systems and controls, it will all make sense. And contrary to popular opinion, all that 'emissions junk' on the engine barely hurts performance. Excepting, perhaps, EGR, but that's something most cars still have today. (The real affect of all that 'emissions junk' was way too many vacuum lines and components on the engine, making diagnostics a pain in the ass). What really bogs down these old cars is how the carbs are adjusted to minimize NOx and unburnt fuel in the exhaust. Makes them run pretty lean, and saps their power. Whereas a fuel injected motor can make adjustments in realtime, and easily compensates for it.
Chrysler came up with the 'Lean Burn' system as a work-around to making realtime adjustments to a carburetor. They found that if you run the mixture super lean, you can (mostly) compensate for it by having a super-variable ignition timing. It worked, but, like I said, nobody understood it, and decided to disable it. That, and in Chrysler's infinite wisdom, they put the Lean Burn computer right on top of the hot, vibrating engine. Guess how that turned out.
I'm curious now what the extent of the carb controls are on this car. It does have an O2 sensor...
