I just put the EZ-EFI system on my tunnel ram.



on the electrical side there were 2 sensor connections on the car that were not on the throttle body, water temp, and O2.

on the electrical side there was +/- and key power aside from the fuel pump.

I elected to run a new fuel system, including tank mounted pump.

Cost? I didnt have to touch the intake, just unbolt the carbs and replace - but dont just think of the cost of the carbs, you'd have to include the jet kit, air bleeds, accel pump kit, wideband O2 sensor, carb book, and the time to make all the necessary changes several times a second to get a carb anywhere near close to where these suckers run.

I can only speak to the EZ system, as it's the one I picked to go with, I didnt want to design a system ( cheaper) or map out my own fuel and timing curves ( more expensive) I wanted to control my own timing and make some adjustments, but not need a laptop to even get moving, or after a significant change in the engine.


I have about 1000 miles on it after several long car event weekends and my exhaust tips are clean, the smell does not kill you from behind the car, and i am getting better mileage...

I'd seriously consider more of these setups on my other cars.
