What else needs to be done when you change out the stock carb on a 88 4.2. Do you have to upgrade ignition system? Does the nutter bypass- bypass the computer and run off the ignition module. What about all the pollution control devices on an the 88 when going to a different carb. On my 80 Dodge I took out a garbage can of wires and computer and installed a 4 wire module, distibutor and different carb. Thanks Gordie
