3800 Manifold Swap (L27 to LN3)

[csjzbelt]

I would like to swap the intake manifold from my L27 1992 Regal (Tuned port) to my L3 1990 LeSabre. My reason for this is that the Regal has better part throttle torque and gas mileage. I know that fuel lines, etc. will need to be rerouted and or constructed/purchased. Would I need to swap injectors? The million dollar question is: Can I swap the computer with the manifold? The regal has digital speedometer, radio, etc. I heard that it can't be done but I don't know. If it can't be done. Can I swap the eprom chip? Maybe I can purchase a chip? Get mine reflashed? Has anyone ever tried this? The Regal has over 180,000 miles on it. The suspension, body, and wiring are going to hell. Whereas the LeSabre has only 75,000 miles, has an excellent body and suspension but is a real pig when it comes to power and mileage. I would really appreciate any help and/or references to companies that could be of potential assistance.
