Can I swap 87 3.8 with a 88 3800? All Buick motors?
I have a good 88 3800(C) motor that I want to install in a car that has a bad 87 3.8(3) motor. I know they will bolt up but I was thinking just change the computer and some wiring(mainly the coil pack). When I took both computers out the 88 has an additional orange (2x16prong)plug on the computer. The only few differences between the cars is the 88 has a digital dash, digital gear indicator, digital (press button) heater controls and auto leveling. They are both ParkAve's. Would it hurt the computer if I tried it anyways without using the additional plug?
