It’s also realistic to think that most any engine swap will be involving some sort of electrical mastermind on hand. With the way the engine/transmission control computer is entangled with the body computer, and with indicators on the dash and gauges, you would effectively loose most all electronic items on the car. Traction control, antilock brakes, and so on... The benz engine upgrade might be easiest to wire into the other systems on the car… but i don’t know of even one person on here that’s swapped a SRT engine in yet and quoted success. Loosing antilock and traction control is no big deal, and fitting in a whole new dash/gauge panel with some different more modification friendly components would not be too hard. This is sounding more like an SEMA job show you would see on the Discovery channel.
