Cage, maybe the guy that asked the question should decide if the info is helpful. The reason I supplied it was that he had not received any other responses to his question.

I have a 1999 magnum 5.9 complete with wiring harness and computer can i put it in my 82 d150 and hook it up to my 3sp auto or do i have to find a 4spd for same year as motor. also do i have to run cat's and o2 sensors since it is all computerized. i would really like to keep all the new accessory upgrades. my other option is to go to a carb and do away with fuel injection. i would like to keep it all as is and just run a 3spd auto 904 i...
