All 360 TBI motors kept the eccentric on the cam for the mechanical fuel pump. What cam are you swapping to? Keep in mind that the stock valve springs will not accommodate a lot of lift. Your real problem is compression, stock should be around 8:1. Don't forget to plug the air ports if you change the exhaust. There's an old Mopar Action article about installing a switch to trigger the lockup feature on the trans, or you could you just swap to a non-lock up converter? You'd be looking at something like a CR20 probably. I don't know about the computer but I do have a TBI wiring diagram saved somewhere if you need it. AFAIK the computer controls the engine and trans only. There may be a cab computer, too.
