i have a 85 f150 with a 4.9... i want to put a 5.0 out of a 99 ford explorer...is this possible..if so were would i start with the wiring on the truck.. would it be better to use the 5.0 trans or the 4.9 4 speed trans ...plaes let me know i need feed back

 

That swap is physically possible but would be an electronic/electrical nightmare.
