Are the motor mounts the same and how would I do a change form a carbureted motor to a EFI motor

 

Motor mounts never changed. What vehicle is this going into?

 

1983 Ford f250

 

To put EFI into the '83 you obviously need a complete EFI motor but you also need a complete EFI wiring harness and computer(PCM), and for that year you also need the speedo cluster and the rear axle as it is the source for vehicle speed input.
