I am building a 1955 Dodge 1/2 pickup on a 1992 Dakota frame with original drive train. The Dakota has a 390 Magnum and automatic transmission. The Dakota has over 250,000 miles on it so I was planning on overhauling both the engine and transmission. The question is when I put everything back together, should I eliminate all the computer “stuff” and just use a carburetor or try to incorporate all the original TBI and ECM?
If I eliminate the ECM what do I need to do to get the transmission to shift correctly?

Maybe I am wrong, but it is kind of appealing to eliminate a lot of those hoses and wires. I am in Montana.

Any and all suggestions would be appreciated.

Thank you
Wayne
