Good morning, so I have a 1992 Silverado (Cheyenne actually) but it has the 4.3 V6, (Throttle body injection) I have now acquired a 1990 Silverado with a 5.7 V8, (throttle body injection) purchased it for some parts I need for the 92. thinking about swapping the v8 into the 92 Cheyenne. Im curious would I also need to swap out the E.C.M? or would the V6 computer work with the 5.7? Anything else I may need to change? Thank you.
