Thanks for adding me. I have a 1984 motorhome with a 454 in it that I will be converting to tbi this winter. If that works out my 1978 dodge d200 with a 440 is next. I have owned/rebuilt a few small block suburbans with tbi so I am a little familiar with the system. My first question is, what year donor vehicle should i look for. My motorhome has a th400 trans and I dont know if the pcm from a later tbi can be used on a non electronic shift 3 speed. Thanks
