I was wondering if anyone could help me out. I have the dreaded 97 f-150 4.2L with well over 200K miles on it. I know that i need to be thinking about a new motor here pretty soon. I am hoping to replace it with a bigger engine but i dont know if it can be done. i understand that i am going to have to replace mytranny and my computer and in order to pass smog it has to be a 97 or newer motor. But i have been told that the electircal is hell. If i replace my motor to a bigger model can my wiring be hooked back up so that my stock instrument panel will work? i live in California where the smog laws are a pain in the *** to say the least and in order to pass smog all my warning lights have to function. I NEED HELP!! Can i change the engine in my truck and still pass smog???
