I am replacing a motor in a 01 flex fuel that snapped the connecting rod and damaged the cylinder wall. The motor I am putting in the 01 flex fuel is a motor out of a 01 non flex. Both are 3.0 vulcans, I am dropping and swapping the whole cradle. What are the differences in the flex fuel and non flex motors? If I swap out the injectors and spark plugs what else would need to be swapped o make the non flex fuel engine a flex fuel capable one?
