Does anyone know the details on swapping a 99 5.7 over to carbureted. I know I would need to change the intake and i am assuming a aftermarket fuel pump as well. What else would have to be done with it to get it to run right. I have had the truck for around 6 or 7 years now and it has sat for at least the last 3. Last year we put a new motor with 84k in it and never drove it or did anything with it because of the damn passlock module went out and cant keep it running. I am thinking i would rather go carbed then have to deal with passlock again
